DrawInfo

Drawinfo allows clients to render mesh more efficiently through LOD's (Level of Detail). Many associate drawinfo with the ability to create moving objects in a map.

Code

The code must be added to the mesh object.

drawInfo dlist # display list for all material sets decorative # older clients with not see this mesh angvel <degrees/sec> # rotation about initial Z axis extents <minX> <minY> <minZ> <maxX> <maxY> <maxZ> sphere <x> <y> <z> <radiusSquared> corner <v> <n> <t> (repeatable) vertex 0.0 0.0 0.0 (repeatable) normal 0.0 0.0 0.0 (repeatable) texcoord 0.0 0.0 (repeatable) lod (repeatable) lengthPerPixel <value> matref <name> (repeatable) dlist # display list for this material set sphere <x> <y> <z> <radiusSquared> points 0 (repeatable) lines 0 1 (repeatable) lineloop 0 1 (repeatable) linestrip 0 1 (repeatable) tris 0 1 2 (repeatable) tristrip 0 1 2 (repeatable) trifan 0 1 2 (repeatable) quads 0 1 2 3 (repeatable) quadstrip 0 1 2 3 (repeatable) polygon 0 1 2 (repeatable) end # matref end # lod end # drawInfo

Valid parameters for drawinfo are:

dlist
decorative	disables drawinfo in older clients
angvel	causes the mesh object to spin at a given rate
extents
sphere
corner	this is a series of points specified by the indexes of the vertices, normals, and texcoords
vertex
normal
texcoord
lod	sections that determine which faces/points will be rendered at specified distances (lengthPerPixel)
lengthPerPixel	distance from which the points will be rendered, 0 is close, .3 is about as far away as is needed
matref	material to use as defined in the materials object
points
lines
lineloop
linestrip
tris	index numbers of corners that create triangles
tristrip	series of points that form a chain of triangles.
trifan	a series of points that create triangles that fan out from a single point. That point, usually in the center, is placed first in the series
quads	points that create 4-sided mesh planes
quadstrip	series of points that create a chain of 4-sided planes. Similarly to tristrips, the series zig-zags between the points, starting in the counter-clockwise direction.
polygon	same as quads except for planes of more than 4 sides.
