- It is highly recommended to compile this project in Release mode. BTW, you can choose either x86 or x64, but personally I prefer x64.
- Because the data files for glossy objects are too large (300MB), we ignore them from git and you may need to generate them manually.
- Since GLM version 0.9.9, GLM default initializes matrix types to a 0-initialized matrix, instead of the identity matrix. From that version it is required to initialize matrix types as:
glm::mat4 mat=glm::mat4(1.0f).
