Function quad

pub fn quad<N: RealField + Copy>(
    width: N,
    height: N,
    usubdivs: usize,
    vsubdivs: usize,
) -> TriMesh<N>

Adds a double-sided quad to the scene.

The quad is initially centered at (0, 0, 0). Its normal is the z axis. The quad itself is composed of a user-defined number of triangles regularly spaced on a grid. This is the main way to draw height maps.

Arguments

• w - the quad width.
• h - the quad height.
• usubdivs - number of horizontal subdivisions. This correspond to the number of squares which will be placed horizontally on each line. Must not be 0.
• vsubdivs - number of vertical subdivisions. This correspond to the number of squares which will be placed vertically on each line. Must not be 0.
