◆ draw_billboard_quad()

object_3d * draw_billboard_quad ( )

extern

create a camera-aligned billboard quad proxy for perfect impostors.

The quad has 4 vertices at unit corners (±1, ±1, 0). Each vertex shader for perfect impostors uses the sign of vert.x / vert.y to select the corresponding edge of the tight axis-aligned bounding box in view space.

Draw primitive: GL_TRIANGLE_STRIP with indices [0,1,2,3]. tri 0 → vertices 0,1,2 tri 1 → vertices 1,2,3
