clip_near, clip_far

clip_near

clip_far

Near and far clipping range of a view. Objects will be cut off along a sharp border when they are either closer or more distant than the given range.

Range:

clip_near: 1 ..unlimited, default 15 .
clip_far: clip_near..unlimited, default 50000 .

Type:

var

Remarks:

Both parameters influence the resolution of the Z buffer, whose range is between clip_near and clip_far. Today, 3D cards normally have 24 bit z buffer resolution. If the clip_near to clip_far ratio exceeds this resolution, sorting errors will become visible on the screen. In that case either increase clip_near or decrease clip_far. This way, the resolution can be adapted to the requirements of a certain game.
The smaller the clip_far range, the fewer objects will be rendered and the better the frame rate.
Particles will be clipped at half the clip_far range. Sky entities and sky blocks are never clipped.
The clip_near range can be reduced for certain entities through the z_near flag.

Example:

camera.clip_near = 5; 	// allows to go very close to objects
camera.clip_far  = 10000; // reduce clip_far for preventing sorting errors
