Usage

From source file:opengl.test.object.object.java

public final void deleteProgram() {
    // disable program
    this.unbind();

    // detach shader
    GL20.glDetachShader(this.programID, this.vertexID);
    GL20.glDetachShader(this.programID, this.fragmentID);
    // delete shader
    GL20.glDeleteShader(this.vertexID);
    GL20.glDeleteShader(this.fragmentID);
    GL20.glDeleteProgram(this.programID);

    // delete vao
    GL30.glBindVertexArray(0);/*from   ww  w  . ja v a 2 s  .  co  m*/
    //GL30.glDeleteVertexArrays(this.vao);
    // delete vbo
    GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0);
    GL15.glDeleteBuffers(this.vbo);

    //delete vbo
    GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, 0);
    GL15.glDeleteBuffers(this.ebo);
