我正在尝试禁用和启用z缓冲区,但是skydome仍然会写入zbuffer。我正在使用DirectXTK,但似乎它不起作用。
CommonStates states(m_Graphics.getDevice());
m_Graphics.getContext()->RSSetState(states.CullNone());
XMMATRIX sphereWorld;
XMMATRIX sphereScale = XMMatrixScaling(200.0f, 200.0f, 200.0f);
XMMATRIX Translation = XMMatrixTranslation(m_Camera.Position().x,
m_Camera.Position().y, m_Camera.Position().z);
sphereWorld = sphereScale*Translation;
m_Graphics.getContext()->OMSetDepthStencilState(states.DepthNone(), 1);
m_shape->Draw(sphereWorld,m_Camera.ViewMatrix(), m_Camera.ProjectionMatrix(), Colors::White, m_texture.Get());
m_Graphics.getContext()->OMSetDepthStencilState(states.DepthDefault(),1);
XMMATRIX cameraInverse = XMMatrixInverse(nullptr, m_Graphics.getViewMatrix());
XMMATRIX translate = XMMatrixTranslation( 2.0f, -3.0f, 2.0f);
XMMATRIX rotation = XMMatrixRotationRollPitchYaw((float)XM_PI/9.0f, (float)XM_PI/0.2f, (float)XM_PI/0.1f);
XMMATRIX world = rotation *translate *cameraInverse;
m_Tiny->Draw(m_Graphics.getContext(), states, world, m_Graphics.getViewMatrix(), m_Graphics.getProjectionMatrix());
m_Graphics.getContext()->RSSetState(states.CullCounterClockwise());
m_Graphics.getContext()->RSSetState(states.Wireframe());
m_Grid.DrawGrid();

GeometricPrimitive
和Model
都在内部设置了所需的渲染状态,包括深度/模板状态作为其API的一部分。
对于GeometricPrimitive,您可以使用setCustomState
回调覆盖默认状态设置。例如,这是一个使用lambda的例子:
m_shape->Draw(sphereWorld,m_Camera.ViewMatrix(), m_Camera.ProjectionMatrix(),
Colors::White, m_texture.Get(), false, [=]
{
m_Graphics.getContext()->RSSetState(states.CullNone());
m_Graphics.getContext()->OMSetDepthStencilState(states.DepthNone(), 1);
});
对于Model,您可以在setCustomState
方法上使用相同的Draw
回调进行快速调整,或者您可以实现高级绘图模式。请参阅wiki
