glDraw<Arrays/Elements>Instanced[BaseInstance].. Indirect Draw: 数据来自GPU, 允许GPU动态生成绘制命令 gl[Multi]Draw<Arrays/Elements>Indirect[Count].. BaseVertex, BaseInstance: baseVertex是EBO索引值的偏移量; baseInstance是InstanceArrays的顶点数据偏移量 glDrawElements<BaseVertex/+/BaseInstance>,glDrawArray...
我们只需要将glDrawArrays和glDrawElements的渲染调用分别改为glDrawArraysInstanced和glDrawElementsInstanced就可以了.这些渲染函数的实例化版本需要一个额外的参数,叫做实例数量(Instance Count),它能够设置我们需要渲染的实例
在第14节我们使用了两次glDrawElements实现了OpenGL实例化,发现这样仍然不太方便,如果需要绘制成千上万的立方体,就需要手写成千上万次的glDrawElements(). 而15节我们知道了glDrawElementsInstanced函数可以支持批量绘制。 我们需要绘制的多个立方体唯一不同的只是转换矩阵,为了达到这个目的,我们只需要定义一组不同的变换矩阵...

After clearing the buffers, we're free to draw whatever we like onto the screen. However, in this example we don't actually draw anything but an empty screen. This will change in subsequent chapters where we will actually start drawing objects, and all of this drawing will happen after the...
Rendering thousands of instanced objects with different geometry using one single indirect draw call instead of issuing separate draws. All draw commands to be executed are stored in a dedicated indirect draw buffer object (storing index count, offset, instance count, etc.) that is uploaded to th...
