Declarations for PTK_Plane struct+functions.
|
int32_t | PTK_Plane_set (PTK_Plane *dst, float nx, float ny, float nz, float d) |
| Set all four values for a point as a convenience function. At least one of nx, ny, nz must be non-zero. More...
|
|
void | PTK_Plane_normalize (PTK_Plane *dst, PTK_Plane *src) |
| Normalize plane parameters so that nx^2+ny^2+nz^2=1. More...
|
|
void | PTK_Plane_transform (PTK_Plane *dst, PTK_Plane *src, const PTK_RigidTransform *M_dst_src) |
| Apply the given rigid transformation to represent the plane (given in src reference frame) in dst reference frame. Output plane will have the same normalization factor as the input plane. More...
|
|
float | PTK_Plane_dot (const PTK_Plane *plane, const PTK_Point *point) |
| Dot product between a plane and a 3d point (x,y,z), which is out = x*nx + y*nx + z*nz - d. If the plane is the normalized, then out is the signed distance of the point from the plane, where positive is in the direction of the normal vector. More...

|
int32_t | PTK_Plane_construct (PTK_Plane *plane, PTK_Point *a, PTK_Point *b, PTK_Point *c) |
| Construct normalized plane from 3 non-colinear points in 3D space by taking cross product. More...
|
|
void | PTK_Plane_projectPoint (PTK_Plane *plane, PTK_Point *proj, PTK_Point *point) |
| Project 3D point onto the plane. More...
