C# Class open3mod.Scene

Represents a 3D scene/asset loaded through assimp. This class contains the aiScene plus some auxiliary structures for drawing. Since assimp is the only source for model data and this is only a viewer, we ignore the recommendation of the assimp docs and use its data structures (almost) directly for rendering.

Méthodes publiques

Méthode	Description
Dispose ( ) : void	Dispose
GetOverrideMesh ( Mesh mesh ) : Mesh
RecreateRenderingBackend ( ) : void	Recreates the rendering backend if needed. This is called after the global rendering backend setting is changed.
Render ( open3mod.UiState state, ICameraController cam, open3mod.Renderer target ) : void	Call once per frame to render the scene to the current viewport.
RequestReconfigureTextures ( ) : void	Requests that texture filters be re-configured as soon as possible. This is called when the texture settings are changed. This method may only be called from the UI thread.
RequestRenderRefresh ( ) : void	Requests the renderer to update next frame even if it seems as if nothing changed. This method may only be called from the UI thread.
RequestReuploadTextures ( ) : void	Requests that all textures be re-uploaded as soon as possible. This is called when the texture settings are changed. This method may only be called from the UI thread.
Scene ( string file ) : System	Construct a scene given a file name, throw if loading fails
SetOverrideMesh ( Mesh mesh, Mesh overrideMesh ) : void	Replace a given mesh with another when drawing. This has immediate effect. Editing tools use this to temporarily replace the mesh being rendered with a preview of the action. Pass null to revert to the original mesh.
SetPivot ( Assimp.Node node, bool realCenter = true ) : void	Set the pivot point for the scene to be at the world position of a given node.
SetSkeletonVisibleOverride ( bool overrideSkeleton ) : void	Turns skeleton visualization on even if it is off in the UI.
SetVisibleNodes ( Dictionary meshFilter ) : void	Sets which parts of the scene are visible. See ISceneRenderer.Render (visibleNodesByMesh parameters) for a description of how the visible set is determined.
Update ( double delta, bool silent = false ) : void	To be called once per frame to do non-rendering jobs such as updating animations.

Private Methods

Méthode	Description
ComputeBoundingBox ( Assimp.Node node, Vector3 &min, Vector3 &max, Matrix4 &trafo ) : void	Helper for ComputeBoundingBox(out Vector3 sceneMin, out Vector3 sceneMax)
ComputeBoundingBox ( Vector3 &sceneMin, Vector3 &sceneMax, Vector3 &sceneCenter, Assimp.Node node = null, bool omitRootNodeTrafo = false ) : void	Calculates the smallest AABB that encloses the scene.
CountVertsAndFaces ( int &totalVertexCount, int &totalTriangleCount, int &totalLineCount, int &totalPointCount ) : void	Counts vertices, points, lines and triangles in the scene.
CreateRenderingBackend ( ) : void
GetPostProcessStepsFlags ( ) : PostProcessSteps
LoadTextures ( ) : void	Populates the TextureSet with all the textures required for the scene.
SetTexturesChangedFlag ( ) : void	Sets a flag for the renderer that at least one of the textures in the scene was changed and needs to be updated. This method may be called from any thread.
