Here some example render of abouttime scene:
Currently it uses glsl because CUDA can't run on AMD, and Nvidia do not support OpenCL 2.0, so bindless textures is the only way I found to access all textures with hardware sampling.
Main API:
Code: Select all
struct LGE_DevSettings
{
void *m_HDC;
void *m_HGLRC;
bool m_threadedGL;
bool m_enableVSync;
};
struct LGE_RuntimeParams
{
glm::vec4 m_cameraRight;
glm::vec4 m_cameraUp;
glm::vec4 m_cameraForward;
glm::vec4 m_cameraPosition;
glm::vec4 m_sunDirection;
glm::vec4 m_sunColor;
unsigned int m_width;
unsigned int m_height;
unsigned int m_spp;
unsigned int m_skyTexture;
float m_time;
float m_secondaryRaysMipmap;
float m_FOV;
float m_denoiseAmount;
};
