.. c:function:: float glm_smc(float s, mat4 m, vec4 c)
|
|
|
|
| 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:
|
|
|
|
.. code-block:: c
|
|
|
|
Bs = glm_smc(s, GLM_BEZIER_MAT, (vec4){p0, c0, c1, p1})
|
|
|
|
Parameters:
|
|
| *[in]* **s** parameter between 0 and 1 (this will be [s3, s2, s, 1])
|
|
| *[in]* **m** basis matrix
|
|
| *[out]* **c** position/control vector
|
|
|
|
Returns:
|
|
scalar value e.g. Bs
