inline float P64::Renderer::getRenderScale()

Render-scale: how many RSP fixed-point world units one meter maps to.

The engine simulates in meters; only at render entry points (model/view matrices, lights, culling, debug draw, particles) are positions multiplied by this factor in float space before the s16.16 fixed-point conversion.

inline float P64::Renderer::getInvRenderScale()
inline void P64::Renderer::setRenderScale(float renderScale)
inline void P64::Renderer::fillModelMatrixFP(
T3DMat4FP *mat,
const fm_vec3_t &scale,
const fm_quat_t &rot,
const fm_vec3_t &pos,
float vertexScale
)

Builds a fixed-point model matrix from a meter-space SRT.

Applies the render-scale and the model’s vertex-scale, so callers (components and user scripts alike) never deal with any scaling.

Parameters:

  • mat – output matrix

  • scale – object scale (unitless multiplier of the model’s authored size)

  • rot – rotation

  • pos – position in meters

  • vertexScale – the model’s vertex scale (see AssetManager::getVertexScale)
