◆ GK_add_key()
| int GK_add_key | ( | float | pos, |
| unsigned long | fmask, | ||
| int | force_replace, | ||
| float | precis | ||
| ) |
Add keyframe.
The pos value is the relative position in the animation for this particular keyframe - used to compare relative distance to neighboring keyframes, it can be any floating point value.
The fmask value can be any of the following or'd together:
- KF_FROMX_MASK
- KF_FROMY_MASK
- KF_FROMZ_MASK
- KF_FROM_MASK (KF_FROMX_MASK | KF_FROMY_MASK | KF_FROMZ_MASK)
- KF_DIRX_MASK
- KF_DIRY_MASK
- KF_DIRZ_MASK
- KF_DIR_MASK (KF_DIRX_MASK | KF_DIRY_MASK | KF_DIRZ_MASK)
- KF_FOV_MASK
- KF_TWIST_MASK
- KF_ALL_MASK (KF_FROM_MASK | KF_DIR_MASK | KF_FOV_MASK | KF_TWIST_MASK)
Other fields will be added later.
The value precis and the boolean force_replace are used to determine if a keyframe should be considered to be at the same position as a pre-existing keyframe. e.g., if anykey.pos - newkey.pos <= precis, GK_add_key() will fail unless force_replace is TRUE.
- Parameters
-
pos position fmaks force_replace precis precision value
- Returns
- 1 if key is added
- -1 key not added

◆ GK_delete_key()
| int GK_delete_key | ( | float | pos, |
| float | precis, | ||

- Parameters
-
pos position precis precision justone delete only one keyframe
- Returns
- number of keys deleted.

◆ Gs_loadmap_as_bitmap()
Load raster map as integer map.
Calling function must have already allocated space in buff for struct BM of wind->rows & wind->cols.
This routine simply loads the map into the bitmap by repetitve calls to get_map_row. Any value other than 0 in the map will set the bitmap. (may want to change later to allow specific value to set)
Changed to use null.
- Parameters
-
wind current window map_name raster map name [out] buff data buffer
- Returns
- 1 on success
- -1 on failure

◆ order_intersects()
ADD.
After all the intersections between the segment and triangle edges have been found, they are in three lists. (intersections with vertical, horizontal, and diagonal triangle edges)
Each list is ordered in space from first to last segment points, but now the lists need to be woven together. This routine starts with the first point of the segment and then checks the next point in each list to find the closest, eliminating duplicates along the way and storing the result in I3d.
- Parameters
-
gs surface (geosurf) first first point last last point vi hi di
- Returns

Ray-Convex Polyhedron Intersection Test.
Originally by Eric Haines, erich@eye.com
This test checks the ray against each face of a polyhedron, checking whether the set of intersection points found for each ray-plane intersection overlaps the previous intersection results. If there is no overlap (i.e. no line segment along the ray that is inside the polyhedron), then the ray misses and returns 0; else 1 is returned if the ray is entering the polyhedron, -1 if the ray originates inside the polyhedron. If there is an intersection, the distance and the nunber of the face hit is returned.
- Parameters
-
org,dir origin and direction of ray tmax maximum useful distance along ray phdrn list of planes in convex polyhedron ph_num number of planes in convex polyhedron [out] tresult distance of intersection along ray [out] pn number of face hit (0 to ph_num-1)
- Returns
- FACE code

Line intersect.
Author: Mukesh Prasad Modified for floating point: Bill Brown
This function computes whether two line segments, respectively joining the input points (x1,y1) – (x2,y2) and the input points (x3,y3) – (x4,y4) intersect. If the lines intersect, the output variables x, y are set to coordinates of the point of intersection.
- Parameters
-
x1,y1,x2,y2 coordinates of endpoints of one segment x3,y3,x4,y4 coordinates of endpoints of other segment [out] x,y coordinates of intersection point
- Returns
- 0 no intersection
- 1 intersect
- 2 collinear

◆ viewcell_tri_interp()
ADD.
In gsd_surf, tmesh draws polys like so:
-------------- | /| | / | | / | | / | | / | | / | | / | | / | | / | | / | | / | |/ | --------------
UNLESS the top right or bottom left point is masked, in which case a single triangle with the opposite diagonal is drawn. This case is not yet handled here & should only occur on edges. pt has X & Y coordinates in it, we interpolate Z here
This could probably be much shorter, but not much faster.
- Returns
- 1 if point is in view region
- otherwise 0 (if masked)
