How can I make an infinite cave using stage3d?
- by ifree
I want to make an infinite cave in my 3d game using flash stage3d. But I got no idea about how to build that cave. Can anyone can give me some solution or hint?
update:
I've tried agal fragment shader like squeae tunnel in shader toy
code:
var fragmentProgramCode:String =
AGALUtils.build()
.mov("ft0","v0")
.div("ft1","ft0.xy","fc3.xy")
.mul("ft2","fc6.x","ft1")
.sub("ft3","ft2","fc5.x")//vec2 p = -1.0 + 2.0 * gl_FragCoord.xy / resolution.xy;
.mul("ft1","ft3.x","ft3.x")
.mul("ft2","ft3.y","ft3.y")
.pow("ft4","ft1","fc6.z")//float r = pow( pow(p.x*p.x,16.0) + pow(p.y*p.y,16.0), 1.0/32.0 );
.pow("ft5","ft2","fc6.z")
.add("ft1","ft4","ft5")
.pow("ft4","ft1","fc6.w")
.mov("ft5","fc5")//uv
.sub("ft1","fc7.x","ft4")
.add("ft5.x","fc7.x","ft1")//uv.x = .5*time + 0.5/r;
.mov("ft6","fc0")//for atan
.atan2("ft5.y","ft3.y","ft3.x",new <String>["fc7.y","fc5.x","fc7.z","fc7.w","fc8.x","fc8.y","fc8.z","fc8.w","fc9.x","fc9.y"],"ft6")
.tex("ft0","ft5","fs0","repeat","linear","nomip")//tex
.mul("ft1","ft4","ft4")
.mul("ft2","ft1","ft4")//r*r*r
.mul("ft1","ft0.xyz","ft2")
.mov("ft0.w","fc5.x")
.mov("oc","ft1").toString()
it can only apply one material,but my project requires different types of material (like floor,ceilling).
so ,I create a 3d model
Is there anyway to make that 3d model render like "infinity cave"? use agal to make each side of cave's texture move?
thanks for your help
