Detailed Description

Factory that generates MeshData for common geometric primitives.

All methods are static — Builder is never instantiated. Generated shapes follow a consistent winding order (counter-clockwise front face) compatible with the engine's default back-face culling state.

CreateCube()

MeshData mnd::Builder::CreateCube ( f32  width, f32  height  )

static

Create a box (6 faces) with the given dimensions.

Parameters

width	Extent along X.
height	Extent along Y (also used for Z in the current implementation).

Definition at line 15 of file Builder.cpp.

CreateFullscreenQuad()

MeshData mnd::Builder::CreateFullscreenQuad ( )

static

Create a clip-space quad covering the entire screen.

Useful for post-processing or Shadertoy-style full-screen fragment shaders. The quad spans NDC [-1, 1] in both X and Y.

CreateRectangle()

MeshData mnd::Builder::CreateRectangle ( f32  width, f32  height  )

static

Create a flat quad with the given dimensions.

Parameters

width	Extent along the X axis.
height	Extent along the Y axis.

CreateTriangle()

MeshData mnd::Builder::CreateTriangle ( f32  size )

static

Create an equilateral triangle centred at the origin.

Parameters

size	Side length.
