Expand description

Draw array of vertices forming primitives

Available primitive-types are:

  • GU_POINTS - Single pixel points (1 vertex per primitive)
  • GU_LINES - Single pixel lines (2 vertices per primitive)
  • GU_LINE_STRIP - Single pixel line-strip (2 vertices for the first primitive, 1 for every following)
  • GU_TRIANGLES - Filled triangles (3 vertices per primitive)
  • GU_TRIANGLE_STRIP - Filled triangles-strip (3 vertices for the first primitive, 1 for every following)
  • GU_TRIANGLE_FAN - Filled triangle-fan (3 vertices for the first primitive, 1 for every following)
  • GU_SPRITES - Filled blocks (2 vertices per primitive)

The vertex-type decides how the vertices align and what kind of information they contain. The following flags are ORed together to compose the final vertex format:

  • GU_TEXTURE_8BIT - 8-bit texture coordinates

  • GU_TEXTURE_16BIT - 16-bit texture coordinates

  • GU_TEXTURE_32BITF - 32-bit texture coordinates (float)

  • GU_COLOR_5650 - 16-bit color (R5G6B5A0)

  • GU_COLOR_5551 - 16-bit color (R5G5B5A1)

  • GU_COLOR_4444 - 16-bit color (R4G4B4A4)

  • GU_COLOR_8888 - 32-bit color (R8G8B8A8)

  • GU_NORMAL_8BIT - 8-bit normals

  • GU_NORMAL_16BIT - 16-bit normals

  • GU_NORMAL_32BITF - 32-bit normals (float)

  • GU_VERTEX_8BIT - 8-bit vertex position

  • GU_VERTEX_16BIT - 16-bit vertex position

  • GU_VERTEX_32BITF - 32-bit vertex position (float)

  • GU_WEIGHT_8BIT - 8-bit weights

  • GU_WEIGHT_16BIT - 16-bit weights

  • GU_WEIGHT_32BITF - 32-bit weights (float)

  • GU_INDEX_8BIT - 8-bit vertex index

  • GU_INDEX_16BIT - 16-bit vertex index

  • GU_WEIGHTS(n) - Number of weights (1-8)

  • GU_VERTICES(n) - Number of vertices (1-8)

  • GU_TRANSFORM_2D - Coordinate is passed directly to the rasterizer

  • GU_TRANSFORM_3D - Coordinate is transformed before passed to rasterizer

@note Every vertex must align to 32 bits, which means that you HAVE to pad if it does not add up!

Vertex order: [for vertices(1-8)] [weights (0-8)] [texture uv] [color] [normal] [vertex] [/for]

@par Example: Render 400 triangles, with floating-point texture coordinates, and floating-point position, no indices @code sceGuDrawArray(GU_TRIANGLES,GU_TEXTURE_32BITF|GU_VERTEX_32BITF,400*3,0,vertices); @endcode

@param prim - What kind of primitives to render @param vtype - Vertex type to process @param count - How many vertices to process @param indices - Optional pointer to an index-list @param vertices - Pointer to a vertex-list
