Description

Represents a simple, non-overlapping contour in field space.

A contour only exists within the context of a rcContourSet object.

While the height of the contour's border may vary, the contour will always form a simple polygon when projected onto the xz-plane.

Example of converting vertices into world space:

// Where cset is the rcContourSet object to which the contour belongs.
float worldX = cset.bmin[0] + vertX * cset.cs;
float worldY = cset.bmin[1] + vertY * cset.ch;
float worldZ = cset.bmin[2] + vertZ * cset.cs;

◆ verts

rcContour::verts

Simplified contour vertex and connection data. [Size: 4 * nverts].

The simplified contour is a version of the raw contour with all 'unnecessary' vertices removed. Whether a vertex is considered unnecessary depends on the contour build process.

The data format is as follows: (x, y, z, r) * nverts

A contour edge is formed by the current and next vertex. The r-value represents region and connection information for the edge. For example:

int r = verts[i*4+3];
 
int regionId = r & RC_CONTOUR_REG_MASK;
 
if (r & RC_BORDER_VERTEX)
{
    // The edge represents a solid border.
}
 
if (r & RC_AREA_BORDER)
{
    // The edge represents a transition between different areas.
}
