struct FrameData

Frame data structure.

Holds data relevant to the current frame being rendered.

Public Functions

inline void upload()

Upload uniforms to the active shader.

Uploads all uniforms stored in the uniforms map to the currently active shader.

Public Members

double width

Frame width.

Holds the width of the current frame.

double height

Frame height.

Holds the height of the current frame.

UniformHashMap uniforms = {{"uTime", 0.0f}, {"uViewMatrix", glm::mat4(1.0f)}, {"uProjectionMatrix", glm::mat4(1.0f)},}

Uniforms for the frame.

Holds a map of uniform names to their corresponding data.

float &time = std::get<float>(uniforms["uTime"])

Reference to the time uniform.
