Unigine::ObjectGuiMesh Class
| Header: | #include <UnigineObjects.h> |
| Inherits from: | Object |
This class allows for rendering GUI onto an arbitrary mesh. Unlike ObjectGui, it can be used to create non-flat displays positioned in the world. If the mesh contains several surfaces, the same GUI will be rendered on each of them. Note that the GUI will be rendered according to the UV mapping of surfaces.

Members
ObjectGuiMesh ( const char * mesh_path, const char * name = 0 ) #
An ObjectGuiMesh constructor. The Gui Mesh will be created on the basis of the mesh loaded from the specified path.Arguments

It's highly recommended NOT to edit the returned mesh.
Return value
A base static mesh used for the object.Ptr<MeshStatic> getMeshForceVRAM ( ) #
Returns the base mesh used for the object and loads it to video memory (VRAM). At that, the static mesh will also be loaded to memory (RAM).Notice
Loading to VRAM must be performed in the main thread only.
Return value
A base static mesh used for the object.Ptr<MeshStatic> getMeshAsyncVRAM ( ) #
Returns the base mesh used for the object asynchronously and loads it to video memory (VRAM). At that, the static mesh will also be loaded to memory (RAM).Notice
Loading to VRAM must be performed in the main thread only.
Return value
A base static mesh used for the object.bool loadAsyncVRAM ( ) #
Asynchronously loads the mesh to video memory (VRAM) if the async streaming mode for meshes is enabled. Otherwise, the forced loading is performed. This method is recommended for implementing your own prefetch system (i.e. asynchronous pre-loading of meshes to video memory before they are used).Notice
Loading to VRAM must be performed in the main thread only.
Return value
true if the mesh is loaded successfully, otherwise false. If the mesh is already loaded to VRAM, true will be returned.bool loadAsyncRAM ( ) #
Asynchronously loads the mesh to memory (RAM) if the async streaming mode for meshes is enabled. Otherwise, the forced loading is performed. This method is recommended for implementing your own prefetch system (i.e. asynchronous pre-loading of meshes to memory before they are used).Return value

- int surface - Mesh surface number.
Return value
true if the internal tree is calculated successfully; otherwise, false.bool asyncCalculateEdges ( int surface ) #

Return value
true if the edges are calculated successfully; otherwise, false.void applyMeshProcedural ( const Ptr<Mesh> & mesh ) #
Sets the specified mesh as the base mesh for the object. The object must be in the procedural mesh mode.Notice
The mesh should contain a single surface. In case if the mesh contains several surfaces, only the one with the 0 index will be used. Thus, the area of the decal will differ from the initial mesh.
Source code (C++)
