◆ contextLost()
virtual void mbgl::style::CustomLayerHost::contextLost |

Called when the system has destroyed the underlying GL context. The deinitialize
function will not be called in this case, however initialize
will be called instead to prepare for a new render.
◆ deinitialize()
virtual void mbgl::style::CustomLayerHost::deinitialize |
( |
| ) |
|
|
pure virtual |
Destroy any GL state needed by the custom layer, and deallocate context, if necessary. This method is called once, from the main thread, at a point when the GL context is active.
Note that it may be called even when the initialize
function has not been called.
◆ initialize()
virtual void mbgl::style::CustomLayerHost::initialize |
( |
| ) |
|
|
pure virtual |
Initialize any GL state needed by the custom layer. This method is called once, from the main thread, at a point when the GL context is active but before rendering for the first time.
Resources that are acquired in this method must be released in the deinitialize
function.
◆ render()
Render the layer. This method is called once per frame. The implementation should not make any assumptions about the GL state (other than that the correct context is active). It may make changes to the state, and is not required to reset values such as the depth mask, stencil mask, and corresponding test flags to their original values. Make sure that you are drawing your fragments with a z value of 1 to take advantage of the opaque fragment culling in case there are opaque layers above your custom layer.
