Syntax:

b2dDrawImageQuadDepthUV:Void(image:Int, x1:Int, y1:Int, z1:Double, u1:Double, v1:Double, x2:Int, y2:Int, z2:Double, u2:Double, v2:Double, x3:Int, y3:Int, z3:Double, u3:Double, v3:Double, x4:Int, y4:Int, z4:Double, u4:Double, v4:Double)

• image : Int — image handle
• x1, y1 : Int — first corner, z1 : Double its depth (0 = nearest, 1 = farthest), and u1, v1 : Double its image point
• x2, y2, z2, u2, v2 — second corner
• x3, y3, z3, u3, v3 — third corner
• x4, y4, z4, u4, v4 — fourth corner

Void

The textured face of a 3D model: a depth per corner, as b2dDrawImageQuadDepth, and an image point per corner, as b2dDrawImageQuadUV. This is the call a mesh loaded with b2dLoadMesh is drawn with, one face at a time.

Returns nothing.

u and v run 0 to 1 across the image, left to right and top to bottom, and are not clamped — values outside that range repeat the edge pixels. Depths are clamped to 0..1 and tested per pixel against the same buffer as b2dDrawQuadDepth and b2dSetDepth, so faces can be drawn in any order.

Pass perspective-correct depths (a + b/z, not raw view z), or a flat face creases along its diagonal — see b2dDrawImageQuadDepth. Where there is no depth buffer (inside a render target, or with a screen shader applied) it draws flat, in call order. Palette-cycling (indexed) images draw nothing.
