How to implement "Texture" inside the "Circle" shape

[tingnapianhai]

Hi, I want to implement the "texture" inside the "circle" shape, anyone knows ?

Code: Select all

1. local function onDraw()


2.     MOAIGfxDevice.setPenColor(0, 0, 1, 1)


3.     MOAIDraw.drawCircle( 100, 100,radius,32)


4.     -- add "texture" code


5. end

Any one knows how to implement it ? Thanks.

Hi tingnapianhai! I think you would find the gl-vertexBuffer sample quite useful: https://github.com/moai/moai-dev/blob/m ... r/main.lua

Try adding vertices so that the final shape forms a circle. (The triangle fan is quite good for making shapes like circles, might be a good idea to google GL_TRIANGLE_FAN for background info.) For reference, the following thread might be useful: need-assistance-using-moaishader-setvertexattribute-t827/

HTH!
