Private final String fragmentTextureShaderCode = 'attribute vec2 aTexPosition '+ // Position of our texture contained in the vertex 'attribute vec4 aPosition '+ // Position of out Vertex What is the best way to achieve this? I am using texure2D to draw the bitmap in my fragment shader, does something need to be added to this to draw the line with a specified color? Any help would be greatly appreciated.Ĭode Relevant to bitmap texturing: private final String vertexTextureShaderCode = I am making my call to draw my line after the call to draw the bitmap to the texture but only the bitmap shows still. I know how vert/tex coordinates work but I am unable to achieve this for some unknown reason. However I would like to draw a line on top of said texture. I am using a texture to render a bitmap to and everything appears fine.
