@ -188,21 +188,45 @@ shade-model - flat, smooth
texture-unit - has several child properties:
unit - The number of an OpenGL texture unit
type - This is either an OpenGL texture type or the name of a
point-sprite - true, false - Whether this should rendered as a point-sprite
type - This is either an OpenGL texture type or the name of a
builtin texture. Currently supported OpenGL types are 1d, 2d,
3d which have the following common parameters:
image (file name)
filter
mag-filter
wrap-s
wrap-t
wrap-r
image (file name)
filter - nearest, linear, [nearest|linear]-mipmap-[nearest|linear]
mag-filter - nearest, linear, [nearest|linear]-mipmap-[nearest|linear]
wrap-s - clamp, clamp-to-border, clamp-to-edge, mirror, repeat
wrap-t - clamp, clamp-to-border, clamp-to-edge, mirror, repeat
wrap-r - clamp, clamp-to-border, clamp-to-edge, mirror, repeat
mipmap-control - control the mipmap on a per-channel basis. Children:
function-r - auto, average, sum, product, min, max
function-g - auto, average, sum, product, min, max
function-b - auto, average, sum, product, min, max
function-a - auto, average, sum, product, min, max
The following built-in types are supported:
white - 1 pixel white texture
noise - a 3d noise texture
environment
mode
color
noise - a 3d noise texture. (size parameter defines size of texture)
light-sprite - a procedurally generated sprite suitable for point lights
cubemap - build a cube-map. Children:
images - build from 6 images. Children: [positive|negative]-[x|y|z]
image - build from a single cross-image
environment
mode - add, blend, decal, modulate, replace
color
texenv-combine
combine-[rgb|alpha] - replace, modulate, add, add-signed, interpolate, subtract, dot3-rgb, dot3-rgba
source[0|1|2]-[rgb|alpha] - constant, primary_color, previous, texture, texture[0-7]
operand[0|1|2]-[rgb|alpha] -src-color, one-minus-src-color, src-alpha, one-minus-src-alpha
scale-[rgb|alpha]
constant-color
texgen
mode - object-linear, eye-linear, sphere-map, normal-map, reflection-map
planes - s, t, r, q
uniform
name
type - float, float-vec3, float-vec4, sampler-1d, sampler-2d,
