Wow, to think I have been compiling code for the last 20 years or so and I instead could have been “ahead of time” compiling it. 20 years wasted…..

This guy eloquently enumerates some reasons I like C++.
Although I do imagine once I get a C++0x compiler, I will like it the most..
D has a lot of promise also…..

Currently learning ObjectiveC/ObjectiveC++

My new employer bought me a shiny new 17″ MacBook Pro.
Currently developing an iPad application.
Needless to say, my biggest obstacles are ObjectiveC/ObjectiveC++.
I am guessing the best way to learn would be re-implementing Orkid’s C++ static introspection/reflection system in terms of ObjectiveC++ to see what ObjectiveC++ actually buys me in dynamic features.
Shame It wont be portable to MSVC++.

Programmer Art

admin — Tue, 26 Jan 2010 19:10:05 +0000

Being a graphics programmer, I often need to make art to test engine features, or familiarize myself with the artist’s pipeline. (Or even because it is fun)
Here is some of that art. They call it programmer art for a reason. ;>

Jan 24, 2010:
ZMan3: (ZBrush 3.5r3)
3rd attempt at using zsphere sculpt with armatures. Also used planar-cut, smooth-valence, inflat, nudge, and pinch. There are so many brushes and so little time to learn ;>.
My anatomy skills leave something to be desired.

Jan 19, 2010:
ZMan2: (ZBrush 3.5r3)
2nd attempt at using zspheres.
Used AUVTile UV mapping, baked normalmaps, applied a CgFX shader and Rigged/Animated it.
This one is kind of demented, you have been warned.
I keep hearing it looks like Silent Hill. I have never played it.
I was going for more twisted than you would find in a commercially available game. I guess I will have to try harder.
http://www.tweakoz.com/portfolio/ezweb/zman2a.avi

Here is ZMan2 looking a little more business like. (Playing with polypaint)

There is more programmer art here (procedural textures).
In the interest of not repeating things on the portfolio I will just link it here.

Software Rasterizer

admin — Thu, 21 Jan 2010 08:57:34 +0000

Jan 21, 2010:
This is the software renderer for Orkid I just started. It is a side project to address my interest in software renderers. I also have a practical need for it, and I will not be rushing this out. I made a simple raytracer for baking lightmaps in the last project I worked on and this renderer when finished will likely take its place. Previously, I had also tried using Pixie and Gelato (REYES renderers) for baking lightmaps, AO, etc…. And while they do work, they were buggy and the way they go about baking to a map with non overlapping UV’s is horribly inefficient. They are designed to render to a camera view or to a ’spatial database’, and in either case you have to turn visibility culling and view based dicing off and they end up doing way too much work (time and memory) for what you need. The ideal baker rasterizes triangles directly into UV space. The ideal baker can still use raytracing or whatever other method it needs to compute the color, but the decision of which pixels to actually compute falls to the UV space rasterizer. I am sure these are issues that Turtle has had to deal with.

This renderer is heavily threaded via a thread pool with concurrent job queues and other atomic building blocks. The transformation pipeline is data parallel (fixed at 64 jobs). Each job handles 1/64th of the polys. Each transformation pipeline job distributes the poly to the appropriate tiles (buckets). Each bucket can atomically add polys without locks, so that each bucket can receive polys from multiple threads efficiently and concurrently. The tile rasterizers are also data parallel. The number of jobs is computed dynamically based on screensize. It divides the screen up into NxN pixel tiles (currently N=128). Task parallelism via the pipeline pattern is coming soon. It will require multi-buffered buckets.

It started out using a Z buffer, recently I switched to a REYES style A buffer/Compositor/Hider for per pixel z sorted translucent fragment lists. I will probably end up making it configurable, the Z buffer is much faster and will still come in handy sometimes. A Renderman like shader language or environment is planned. I plan on doing light shaders, surface shaders, atmospheric and volume shaders. I’m not sold on displacement shaders yet (normalmaps seem fine for the kind of things I plan on using this for).. I will also add in a trace family of functions for ray-tracing, AO and SSS baking.

All performance figures are for a dual Xeon 2.26ghz E5520 machine with all 8 cores (16 ht cores) enabled running Windows7 X64 with a 32bit executable. It is not SIMD optimized yet. I am also not using indexed triangles yet (and therefore also not using a post xform cache). While performance is important, I will be primarily aiming for image quality. Once I get the basic features ironed out and solid, I am going to move a few pipeline stages over to OpenCL/CUDA. I could probably save a lot of time by using CUDA/OpenCL directly as the shading language. The model is shown here with only back faces so you can see the internal complexity of the object (usually it would be hidden by the outer walls). The test model has approximately 350K triangles.

Note: some video captures are colored incorrectly because Fraps has a swizzling/surface format bug with direct2d, I believe R and B are swapped. I have recently switched to using ffmpeg, these captures are both fine and dandy.

(Version: Feb04)

Spherical environment mapping working in OpenCL with 2d image objects and samplers. I was very surprised to find out OpenCL does not have float3 support, so I have to use float4 for normals. Also the NVidia OpenCL compiler is very buggy. It chokes horribly on commented out code.

Next I am going to see if porting the triangle scan converter and aa resolver to OpenCL help performance.
Sharing buffers between stages should get me less host<>opencl data movement traffic.
Or maybe I should do a ray marching volume shader. So many choices…

(Version: Feb01)

The Renderer is now computing fragments in OpenCL. What a PITA! Dealing with broken NVidia SDK’s (I had to ‘hot rod’ the NVidia SDK with the OpenCL headers and libs from the ATI stream SDK (see this post ). At least it works now!

It is currently a bit slower on a Geforce260core216 than a 2x Xeon E5520, This is most likely due to:

Very simple shader (barycentric->color with no conditionals), => The math/overhead ratio is lower. ( source code to shader: here ) .
The need for locking (OpenCL cannot enqueue kernels from multiple threads, so only 1 tile buffer can access the OpenCL device at a time). The CPU version needs absolutely no locking, as it relies upon atomic operations when dealing with concurrent containers.
PCI-Express data movement overhead.
Bottleneck elsewhere in the pipeline.
Shiny new untested OpenCL drivers?.

The Performance gap should shift drastically into OpenCL’s favor when I get a more complicated shader in..

Heres a more recent performance table.
A-Buffer enabled.
Backface culling off.
All fragments 50% translucent for A-Buffer performance testing.
32×32 tile size (or 32×32x3×3 for 9xAA).
16 CPU threads.

OpenCL (hacked NVIDIA SDK 2.3a with ATI stream headers and static library).
Local WorkGroup Size: 512 (or 1 – does not make a difference)
Still ~350K triangles without shared vertices.

Our second shader! It is written in C++ (not in a shading language). Normals interpolation working. Texture/Samplers working. Spherical environment mapping, etc… You can really see the A-Buffer’s perfect depth sorted translucency in this video.

720p Always

(Version: Jan28)

Our first shader! It is written in C++ (not in a shading language). The full shading pipe is not yet implemented. That said, it is still a shader!
It is a composite of object-space face normals, a grid in object-space, and a single octave of object-space noise modulating another grid.
Spent way too much time fiddling with ffmpeg and YouTube trying to get a decent quality video. At least now I have a reasonable transcoding process ironed out..

Also recommended in 1280×720.

(Version: Jan26)

The A-Buffer is working and the Z-Buffer is disabled. Obviously, performance dropped quite a bit. Every fragment now has to allocate a rend_fragment struct from a fragment pool and add it to a per pixel linked list. There is a single fragment pool per tile buffer (and therefore 1 per thread). The fragment pool does help quite a bit by batching up heap allocations. The fragment pools have a reset function which just resets counters so that next frame the recycled fragments are used first and heap traffic is greatly reduced. After the tile has computed all fragments then they are composited in the AA resolve step. I don’t have fragment Z sorting working yet, I am undecided on if it will happen on the fly at list addition or as a postprocess in the composite phase. Maintaining good data and instruction cache locality would lead me to try the postprocess phase first (probably using a radix sort).

I recommend this one in 1280×720.
Here you can see the A-Buffer working.
The triangles are colorized with their barycentric coordinates, this help visualize the mesh topology, and also depth complexity.

(Version: Jan25)
Here is the current performance table with Perspective correct UV interpolation and differing AA modes.
Note: I am not filling the screen, the performance stats represent the screen fill coverage that you see in the videos. However, Overdraw and AA-Resolve are included.
There is 1 tile buffer per thread in the threadpool (currently 32). With fixed assignment, this removes the need for locking on tile buffers and still allows concurrency.

AAMode/Res	Frames/Sec	MPix/Sec	TileBuffer Ram (RGBAZ) (32×128x128xAA)

Screenshot of 25XAA

(Version: Jan24)
It currently runs at interactive rates (~25-28hz) at 1920×1080.
Currently it is more geometry bound than fill bound, this will change of course when I start sampling textures and computing shaders.

(Version: Jan21)
You can see that polys that span tile boundaries are currently dropped, this will be fixed soon.

This is just a little tool I made to debug my rasterizer’s pixel coverage and fill rules.

(Newer Version)
Fixed the fill rules

(Older Version)
Apparently, I still have some debugging to do with it ;>

Shaders

admin — Fri, 15 Jan 2010 00:31:19 +0000

Here are some of the shaders I have worked on in the past.
In some cases I will show programmer art, as the point is to showcase the shader and not the specific model

There are some new shaders coming soon.
I have to wait until our last game (GravJet Racing) passes XBLA cert. As soon as it does, I can put them up.. Stay tuned..
for now look here. I did all the shaders for that game.
I am allowed to show these privately to potential employers, if you are interested contact me at michael at tweakoz.com.

Here are some more miscellaneous shaders I have written in 2007-2009. Some of them were originally shader bugs, and I thought they looked cool, so I kept them around… The model’s shaders have In-Maya CgFx and In-Engine HLSL/CgFx versions.

Multilayered with normal maps
Octave noise
A few fullscreen effect shaders
- Ghostly
- Glow
- Afterlife
- Painterly

Frogman Shader (2007)
This is really a modified and abused parallax shader. The subdermal layer is created by animating the parallax depth parameter. There are also 3 normal maps, the main artist supplied normal map, and 2 detail normal maps. You can see the normal maps change strength in the video. The model and texturing was done by Kenneth Anderson at Santa Cruz Games.

Anisotropic Shaders

Music

admin — Tue, 12 Jan 2010 14:00:38 +0000

If you can tolerate some repetiveness, bad lyrics and sometimes bad timing, then here is some of the music I do. I wish I had more time to spend on it. Crunching in the games industry sucks up all my time. Most of the items here are more like song fragments or sketches (Again, due to lack of time). The average length of time spent working on each piece is probably around 4-8 hours, from initial composition to mixing. The repetitiveness comes in because of good ol copy and paste. The bad timing because I don’t practice enough. And the bad lyrics, well, I’m not a poet, and I certainly know it (I usually spend about 1 or 2 minutes on the lyrics). And the singing, uggh – Good thing I have a day job ;> Seriously though, If I spent more time on it I’m sure I could come up with something half decent. As a general rule I do not used canned loops, though there are a few exceptions.
And yes, I really do go a year or two between writing song fragments (you can tell;>). My new years resolution for 2010 is to spend some more time on da music. I am guessing a well done single song will probably take on the order of 100hrs of work. Maybe I will actually get a full song out this year.

This material has not been mastered properly.
For best results listen to it on some nice bassy headphones with a nice headphone amp. (Like which I engineered it on)

This is an ambient collage made from some recordings at our party in 2003 and some random older material.
It brings new meaning to the term “mashup”.
I will warn you in advance, it is 15 minutes long and it goes all over the place.
Much of it is random, but it gets surprisingly cohesive in a few spots and somehow a progression emerged.
Collage is fun, for 12 hours of arranging and mixing I get 15 minutes of music (if you can call it music ;>).
It started out as an exercise in dense arranging and mixing.
How many layers can you cram in and still have enough clarity to make out the pieces?
Because of the mix density, a nice set of headphones are recommended for hearing all the details.
I have a ton of old DATS to go thru, I think I will to do another..
I am a little at odds between the heavier effected version and the cleaner version, so I put both up.
