ShadowCaster
ShadowCaster is an utility I made for learning purpose. Its aim is to compute shadows and texture for a specified heightmap, using various algorithms.
These are the features of ShadowCaster:
- Five shadow generation techniques
- Two texture generation techniques
- Four blending techniques (used to blend the shadowmap with the colormap)
- You can set the position of the light emitter in any point of the map
- Customizable shadow decay(length) and darkness
- OpenGL 3D Viewer (needs a LOT of optimizations!!)
- Limited to 256x256 maps :(
