cpMat2x2New cpMat2x2 cpMat2x2New(cpFloat a, cpFloat b, cpFloat c, cpFloat d): @} @defgroup cpMat2x2 cpMat2x2 2x2 matrix type used for tensors and such. @{
cpv cpVect cpv(const cpFloat x, const cpFloat y): Convenience constructor for cpVect structs.
cpvadd cpVect cpvadd(const cpVect v1, const cpVect v2): Add two vectors
cpvclamp cpVect cpvclamp(const cpVect v, const cpFloat len): Clamp v to length len.
cpvcross cpFloat cpvcross(const cpVect v1, const cpVect v2): 2D vector cross product analog. The cross product of 2D vectors results in a 3D vector with only a z component. This function returns the magnitude of the z value.
cpvdist cpFloat cpvdist(const cpVect v1, const cpVect v2): Returns the distance between v1 and v2.
cpvdistsq cpFloat cpvdistsq(const cpVect v1, const cpVect v2): Returns the squared distance between v1 and v2. Faster than cpvdist() when you only need to compare distances.
cpvdot cpFloat cpvdot(const cpVect v1, const cpVect v2): Vector dot product.
cpveql cpBool cpveql(const cpVect v1, const cpVect v2): Check if two vectors are equal. (Be careful when comparing floating point numbers!)
cpvforangle cpVect cpvforangle(const cpFloat a): Returns the unit length vector for the given angle (in radians).
cpvlength cpFloat cpvlength(const cpVect v): Returns the length of v.
cpvlengthsq cpFloat cpvlengthsq(const cpVect v): Returns the squared length of v. Faster than cpvlength() when you only need to compare lengths.
cpvlerp cpVect cpvlerp(const cpVect v1, const cpVect v2, const cpFloat t): Linearly interpolate between v1 and v2.
cpvlerpconst cpVect cpvlerpconst(cpVect v1, cpVect v2, cpFloat d): Linearly interpolate between v1 towards v2 by distance d.
cpvmult cpVect cpvmult(const cpVect v, const cpFloat s): Scalar multiplication.
cpvnear cpBool cpvnear(const cpVect v1, const cpVect v2, const cpFloat dist): Returns true if the distance between v1 and v2 is less than dist.
cpvneg cpVect cpvneg(const cpVect v): Negate a vector.
cpvnormalize cpVect cpvnormalize(const cpVect v): Returns a normalized copy of v.
cpvperp cpVect cpvperp(const cpVect v): Returns a perpendicular vector. (90 degree rotation)
cpvproject cpVect cpvproject(const cpVect v1, const cpVect v2): Returns the vector projection of v1 onto v2.
cpvrotate cpVect cpvrotate(const cpVect v1, const cpVect v2): Uses complex number multiplication to rotate v1 by v2. Scaling will occur if v1 is not a unit vector.
cpvrperp cpVect cpvrperp(const cpVect v): Returns a perpendicular vector. (-90 degree rotation)
cpvslerp cpVect cpvslerp(const cpVect v1, const cpVect v2, const cpFloat t): Spherical linearly interpolate between v1 and v2.
cpvslerpconst cpVect cpvslerpconst(const cpVect v1, const cpVect v2, const cpFloat a): Spherical linearly interpolate between v1 towards v2 by no more than angle a radians
cpvsub cpVect cpvsub(const cpVect v1, const cpVect v2): Subtract two vectors.
cpvtoangle cpFloat cpvtoangle(const cpVect v): Returns the angular direction v is pointing in (in radians).
cpvunrotate cpVect cpvunrotate(const cpVect v1, const cpVect v2): Inverse of cpvrotate().
