return;
}
glActiveTexture(GL_TEXTURE0);
glEnable (GL_TEXTURE_2D);
if(currentTexture != texture) {
OpenGLTexture *glTexture = (OpenGLTexture*)texture;
glBindTexture (GL_TEXTURE_2D, glTexture->getTextureID());
}
currentTexture = texture;
}示例2: doRender
void OpenGLRenderManager::doRender(IVertexBuffer* _buffer, ITexture* _texture, size_t _count)
{
OpenGLVertexBuffer* buffer = static_cast<OpenGLVertexBuffer*>(_buffer);
unsigned int buffer_id = buffer->getBufferID();
MYGUI_PLATFORM_ASSERT(buffer_id, "Vertex buffer is not created");
unsigned int texture_id = 0;
if (_texture)
{
OpenGLTexture* texture = static_cast<OpenGLTexture*>(_texture);
texture_id = texture->getTextureID();
//MYGUI_PLATFORM_ASSERT(texture_id, "Texture is not created");
}
glBindTexture(GL_TEXTURE_2D, texture_id);
glBindBuffer(GL_ARRAY_BUFFER, buffer_id);
// enable vertex arrays
glEnableClientState(GL_VERTEX_ARRAY);

// before draw, specify vertex and index arrays with their offsets
size_t offset = 0;
