Members

---

DecalMesh ( ) #

Constructor. Creates a new Mesh Decal.

DecalMesh ( string path ) #

DecalMesh constructor. Creates a Mesh Decal with a source mesh loaded from the specified file.

Arguments

• string path - Path to the source mesh file.

static int type ( ) #

Returns a DecalMesh type identifier.

Return value

Type identifier.

Mesh GetMeshCurrentRAM ( ) #

Returns the current source mesh used for the object and loaded to memory (RAM).

Return value

A current source mesh used for the object.

MeshRender GetMeshCurrentVRAM ( ) #

Returns the current render mesh used for the object and loaded to video memory (VRAM).

Return value

A current render mesh used for the object.

Mesh GetMeshForceRAM ( ) #

Returns the source mesh used for the object and loads it to memory (RAM) immediately.

Return value

A source mesh used for the object.

MeshRender GetMeshForceVRAM ( ) #

Returns the render mesh used for the object and loads it to video memory (VRAM) immediately. At that, the static mesh will also be loaded to memory (RAM).

Return value

A render mesh used for the object.

Mesh GetMeshAsyncRAM ( ) #

Returns the source mesh used for the object and loads it to memory (RAM) asynchronously.

Return value

A source mesh used for the object.

MeshRender GetMeshAsyncVRAM ( ) #

Returns the render mesh used for the object and loads it to video memory (VRAM) asynchronously. At that, the static mesh will also be loaded to memory (RAM).

Return value

A render mesh used for the object.

Mesh GetMeshProceduralRAM ( ) #

Returns the procedural source mesh used for the object and loads it to memory (RAM) using the specific streaming mode for procedural meshes. A procedural mesh is a mesh created via code, such meshes have a specific streaming mode — they are always kept in memory after creation and never unloaded until the object is destroyed via code or the mesh returns to its normal mode (streaming from a source file). Changing of the static mesh is possible only if it is in the procedural mode.

Return value

A procedural source mesh used for the object.

MeshRender GetMeshProceduralVRAM ( ) #

Returns the procedural render mesh used for the object and loads it to video memory (VRAM) using the specific streaming mode for procedural meshes. A procedural mesh is a mesh created via code, such meshes have a specific streaming mode — they are always kept in memory after creation and never unloaded until the object is destroyed via code or the mesh returns to its normal mode (streaming from a source file). Changing of the static mesh is possible only if it is in the procedural mode.

Return value

A procedural render 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).

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 video memory before they are used).

Return value

true if the mesh is loaded successfully, otherwise false. If the mesh is already loaded to RAM, true will be returned.

bool LoadForceVRAM ( ) #

Performs force-loading of the mesh to video memory (VRAM) immediately. The forced loading to VRAM is performed in the main thread.

Return value

true if the mesh is loaded successfully, otherwise false. If the mesh is already loaded to VRAM, true will be returned.

bool LoadForceRAM ( ) #

Performs force-loading of the mesh to memory (RAM) immediately.

Return value

true if the mesh is loaded successfully, otherwise false. If the mesh is already loaded to RAM, true will be returned.

bool AsyncCalculateNodes ( int surface ) #

Asynchronously calculates the mesh surface internal spatial tree used for quick calculation of collisions and intersections. This method is recommended for implementing your own prefetch system (i.e. asynchronous pre-loading of meshes to memory before they are used).

Arguments

• int surface - Mesh surface number.

Return value

true if the internal tree is calculated successfully; otherwise, false.

bool AsyncCalculateEdges ( int surface ) #

Asynchronously calculates the edges of the mesh surface geometry. This method is recommended for implementing your own prefetch system (i.e. asynchronous pre-loading of meshes to memory before they are used).

Arguments

• int surface - Mesh surface number.

Return value

true if the edges are calculated successfully; otherwise, false.

bool ApplyMeshProcedural ( Mesh mesh ) #

Sets the specified mesh as the source mesh for the object.

Arguments

• Mesh mesh - Source mesh to be applied.

int GetStatDrawCalls ( ) #

Returns the number of draw calls (DIP) for the decal during the last frame.

Return value

Number of draw calls (DIP) for the decal during the last frame.

int GetStatDrawCountViewport ( ) #

Returns the number of times the decal was drawn in the viewport last frame.

Return value

Number of times the decal was drawn in the viewport last frame.

int GetStatDrawCountReflection ( ) #

Returns the number of times the decal was drawn during reflections rendering in the last frame.

Return value

Number of times the decal was drawn during rendering in the last frame.

int GetStatDrawCountShadow ( ) #

Returns the number of times the decal was drawn during shadows rendering in the last frame.

Return value

Number of times the decal was drawn during shadows rendering in the last frame.

long GetStatFrame ( ) #

Returns the number of Engine frame, in which the decal was drawn last time.

Return value

Number of frame, in which the decal was drawn last time.
