Examples with VertexBufferObject com.badlogic.gdx.graphics.glutils.VertexBufferObject used on opensource projects

Example 1 with VertexBufferObject

use of com.badlogic.gdx.graphics.glutils.VertexBufferObject in project libgdx by libgdx.

the class VertexBufferObjectShaderTest method create.

@Override
public void create() {
    //@off
    String vertexShader = "attribute vec4 a_position;    \n" + "attribute vec4 a_color;\n" + "attribute vec2 a_texCoords;\n" + "varying vec4 v_color;" + "varying vec2 v_texCoords;" + "void main()                  \n" + "{                            \n" + "   v_color = vec4(a_color.x, a_color.y, a_color.z, 1); \n" + "   v_texCoords = a_texCoords; \n" + "   gl_Position =  a_position;  \n" + "}                            \n";
