* @brief helper function to calculate S*M*C multiplication for curves
|
|
*
|
|
* This function does not encourage you to use SMC,
|
|
* instead it is a helper if you use SMC.
|
|
*
|
|
* if you want to specify S as vector then use more generic glm_mat4_rmc() func.
|
|
*
|
|
* Example usage:
|
|
* B(s) = glm_smc(s, GLM_BEZIER_MAT, (vec4){p0, c0, c1, p1})
|
|
*
|
|
* @param[in] s parameter between 0 and 1 (this will be [s3, s2, s, 1])
|
|
* @param[in] m basis matrix
|
|
* @param[in] c position/control vector
|
|
*
|
|
* @return B(s)
