Dazed Software Renderer
English|中文
Features
-
pure win32, no dependency.
-
scriptable shader function.
-
z-buffer test.
-
perspective correction lerp.
-
interactive render sence.
-
easy texture mapping.
-
.obj mesh parser.
Conclusion
Dazed software renderer is a simple study result of computer graphics. It is very tiny and very simple, but including the basic rasterization rendering pipeline. Deepening understanding of render pipeline.
I start from tutorial: https://github.com/ssloy/tinyrenderer/wiki ,after that, i got a render picture:
Then i use win32 function to create a real-time renderer window. There is an elegant repository: https://github.com/skywind3000/mini3d , i study win32 windows management ways from it.
Tips
-
Take care of RHS/LHS projection Matrix, the project matrix in tinyrender is too simple. you actually need aspect, fovy and other parameters to init a projection Matrix, if you use RHS, remember to multiply -1 after SV_coord.
-
TinyRenderer tutorial donot include a perspective correction lerp. please use 1/w which is linear to lerp uv, light, and other vertex attribute.
This is a correct perspective lerp light-intensity render result:
Finally, I down load the free miku model from https://sketchfab.com/3d-models/hatsune-miku-chibi-w-stand-7310aaeb8370428e966bdcff414273e7 , recompute vertex normal in houdini, Get the render result:
