This function sets the amount of geometric sub-division to use when drawing a shader element with dxDrawImage.

Using tessellation allows a shader to manipulate the shape of the rendered image at each sub-division boundary.

Syntax

bool dxSetShaderTessellation ( element theShader, int tessellationX, int tessellationY )

Required Arguments

  • theShader: The shader element whose tessellation is to be changed
  • tessellationX: The number of sub-division points along the X axis. Range is 1 to 500.
  • tessellationY: The number of sub-division points along the Y axis. Range is 1 to 500.

Returns

Returns true if the shader element's tessellation was successfully changed, false otherwise.

Example

myShader = dxCreateShader( "hello.fx" )
dxSetShaderTessellation ( myShader, 16, 16 )
