This is a very tiny software rasterization applicaiton for understanding basic CG knowledge
#Main Features
- movable camera
- Perspective correct interpolation
- Back-face culling
- Homogeneous clipping
- Back-face culling
- Blinn-Phong shading
- Cubemap skybox
- basic obj model loader
-
Finally, I found that it's the Perspective correct interpolation problem
To be faster, I put the Zt in the parenthesis, which means I use alpha' = alpha / Za * Zt
In this way, I will no longer care the Perspective correct, just use alpha', beta', gamma' to compute
But the error comes.. -
After fix bugs
https://github.com/SunXLei/SRender
- math lib
- platform io
- setup basic framework and draw basic triangle to verity
- camera and verify rotate and drag
- rasterize func
- texture load
- basic model, basic shader to handle data
- fix bugs
- complete pipeline including backface clipping, clipping space interpolate and clipping, larger z clipping
- fix bugs
- load complex model and their resources
- Blin-PhongShader
--------------------------- current -------------------- - PBR, IBL shader
- try TBB or any multi thread methods to speed up
