linearly v0.32.0 / mat4 / fromRotationTranslationScaleOrigin
Function: fromRotationTranslationScaleOrigin()
fromRotationTranslationScaleOrigin(
rot,trans,scale,origin):number[]
Creates a matrix from a quaternion rotation, vector translation and vector scale, rotating and scaling around the given origin This is equivalent to (but much faster than):
mat4.identity(dest);
mat4.translate(dest, vec);
mat4.translate(dest, origin);
const quatMat = mat4.create();
quat4.toMat4(quat, quatMat);
mat4.multiply(dest, quatMat);
mat4.scale(dest, scale)
mat4.translate(dest, negativeOrigin);
Parameters
• rot: quat
Rotation quaternion
• trans: vec3
Translation vector
• scale: vec3 = vec3.one
Scaling vector
• origin: vec3 = vec3.zero
The origin vector around which to scale and rotate
Returns
number[]
