示例1: draw
//--------------------------------------------------------
void CShaderNode::draw()
{
CC_NODE_DRAW_SETUP();
//传递uniform变量
CCGLProgram* shader = getShaderProgram();
shader->setUniformLocationWith2f(m_unUniformResolution, m_tagResolutionPos.x, m_tagResolutionPos.y);
shader->setUniformLocationWith1i(m_unUniformTex0, 0);
glUniform1f(m_unUniformTime, m_fTime);
//获取attribute变量
CCSize size = this->getContentSize();
float w = size.width;
float h = size.height;
ccGLBindTexture2D(m_pTexture); //绑定纹理到槽位
glCopyTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, 0, 0, w, h, 0); //截取屏幕数据到纹理
glEnableVertexAttribArray(m_unAttributePosition);
//传递attribute变量
GLfloat vertices[12] = {
0, 0, //左下0
w, 0, //右下1
w, h, //右上2
0, 0, //左下0
0, h, //左上3
w, h, //右上2
};
glVertexAttribPointer(m_unAttributePosition, 2, GL_FLOAT, GL_FALSE, 0, vertices);
glVertexAttrib4fv(m_unAttributeColor, m_fColor);
//绘制
glDrawArrays(GL_TRIANGLES, 0, 6);
