A “material” represents a collection of properties and settings that, when applied through the use of a “shader” (a small program/subroutine that describes how the settings are used), describe how the geometry associated with a 3D object interacts with light and ultimately what the surface of that 3D object looks like when rendered.

DzRenderMgr::RenderPriority : renderPriority

The render priority for the material. Render priority controls the order in which materials are handled during a render. The higher the priority, the earlier the material will be handled. If several materials have the same render priority, those materials will be handled in an arbitrary order.

The render priority on all nodes that use this material (this will include the top-level skeleton node when dealing with figures) can automatically be set to match the material's new priority by calling enablePropagateRenderPriorityToNodes() with true before calling this method.

The default render priority is DzRenderMgr::RENDER_PRIORITY_NORMAL.

void : enablePropagateRenderPriorityToNodes( Boolean propagate )

Parameter(s):

• propagateOnOff - Whether or not the new priority value should be applied to all nodes that use this material (this will include the top-level skeleton node when dealing with figures).

void : setBakedMap( DzTexture img )

Set the 'baked' shader map for this material. This overrides any current material settings and just draws the map. This is useful for representing the results of off-line shaders that can not be represented in OpenGL - the results of the shader are 'baked' onto a texture map, and then applied to the material with this function.

Parameter(s):

• img - The image that will be applied to the material instead of the current material settings. If NULL, the current baked map is cleared and the material is returned to using its current settings.

Set the color ('texture') map for this material.

---

void : setSmoothingOn( Boolean onOff )

Sets whether or not smoothing is enabled for the material.

Parameter(s):

• onOff - If true, smoothing is applied according to the smoothing angle. If false, no smoothing is applied to the material.

---

Boolean : shouldAlwaysEmbed()
