This article needs checking. |
Reason(s): The example should depict better how does this function actually work with a texture. |
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 )
OOP Syntax Help! I don't understand this!
- Method: shader:setTessellation(...)
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 )
