Functions for 2, 3 and 4 dimensional vectors are defined. Functions for 2x2, 3x3 and 4x4 sized matrices are defined. Quaternions are available and interchangeable with 4 dimensional vectors.
If more types are needed, CCV_DEFINE_VEC(n) can be used to define n dimensional vectors and CCV_DEFINE_MAT(n) can be used to define nxn sized matrices.
The typedef ccvType is float by default, but can be any floating point type. All vector and matrix elements will be of the type ccvType. Functions for sine, cosine, tangent and square root can also be changed. By default, functions from math.h are used.
Function and type names can be changed if preferred. By default, a 3 dimensional vector type is defined as vec3, and the function to normalize it is defined as vec3 vec3Normalize(vec3 v). This can be changed to v3 v3_normalize(v3 v) for example by altering macro definitions at the beginning of the file.
