int Flags(LXtObjectID self)

This is the interface used to get the flags, vector type and 2 evaluation interfaces. ‘Flags’ textures have a number of flags that indicate how the texture behaves in general. For examples flags are used to indicate if a texture references clip or locator items, or if it references things like vmaps. ‘VectorType’ returns the texture global vector type. NOTE: this should probably be implemented as ISA ‘Preview’ is used to process item events and returns preview change flags. ‘PrepFilter’ adds the channels for the texture modifier ‘AllocFilter’ allocates a full texture filter object ‘AllocTexture’ allocates a simpler texture evaluation object.

Mask layers have a specific interface used to compute partitioning. Partitioning is done by ptags and objects, it can use either or both at the same time. For example, a mesh can be partionned by a material name and an object ID, so you could have ptag:”Default”, object:”Mesh A”. This would apply the mask on all polygons with the “Default” material ptag on object “Mesh A”.

• Tag This returns the polygon tag type used for partioning.

• String This returns the name used on polygon tags, like the material name.

• Object This returns item ID of the object used for partitioning.

• Type This returns the shader type.

• Stack This returns the mask evaluation sub-stack, that is the stack for all the mask’s child items. N5: Object() returns the internal item pointer. N5: Stack() returns the internal EvalStackID (for which we currently have no COM option!).

A value texture is a simple type of texture, also called procedural although that’s incorrect since value textures can come from data sources other than algorithms. A value texture provides a scalar, color or vector value at every point on a surface.

• SetupChannels This is called when the item type is first defined to determine the channels that should be added to the item definition.

• LinkChannels This is called with an ILxEvaluation interface and the texture should add any channels that it wants to read.

• ReadChannels This is called with an ILxAttributes interface so the texture can read any of the values that it needs at the current time. The values read should be cached (along with any other needed scratch space) to an allocated block of data returned indirectly.

• Customize After channels are read the value texture can request surface features and sample vector packets. No guarantees.

• Evaluate This is called during rendering for every sample where the value texture applies. The function should use the spot parameters of the sample in the input packet, and write results to the output packet.

• Cleanup Frees the data block allocated by ReadChannels() method.

• LinkSampleChannels This is called with an ILxEvaluation/ILxAttributes interface and the texture should add any channels that it wants to read on a per-sample basis. This method should also be used to store a copy of the CLxUser_Attributes derived from the nodalEtor passed in. If your ‘evalData’ is derived from the CLxSampleRendData user class, then you can simply perform an ‘rd->at.set (nodalEtor)’ as shown in the example below.

• IsSampleDriven For efficiency, it helps if the shading system knows if a texture has any channels that are per-sample driven. If not, much of the per-sample setup can be skipped, making rendering faster. This will be called to ask if the texture is in any way sample-driven for the current pass. This can be determined by using the CLxUser_NodalService::AnyDrivenChans() method.

• Setup This is called when a new shader slice is created. It may be called multiple times when setting up a render or preview - once for each new slice.

LxResult SetupChannels(LXtObjectID self, LXtObjectID addChan)

A component shader is a simple type of shader that sets the shading component and output packets.

• SetupChannels This is called when the item type is first defined to determine the channels that should be added to the item definition.

• Evaluate This is called during rendering for every sample where the shader applies. The function gets the raycast object and the shade component and output packets that it can alter.

• SetShadeFlags This is called before rendering and allows a component shader to set the shading flags, which allows it do things like be transparent to shadow rays or be double sided, or set a light linking group.

• SetOpaque This allows the shader to override its “opaqueness”. For shaders that use other shaders as inputs, such as the cel and halftone shader, it is necessary that they are not opaque.

• CustomPacket This allows the shader to specify a custom packet it GETS.

Public Functions

LxResult SetupChannels(LXtObjectID self, LXtObjectID addChan)

A custom material is a more advanced type of shader. It can change material attributes AND perform its own shading. The custom material looks like a material item in the shader tree but it also has an implicit shader that is evaluated after the base shader. Because it is a material item it can textured, the texturing works by defining a custom packet (in which the texturable attributes are stored) and number of texture effects, one for each texturable attribute. The easiest way to add such effects is through the ILxPacketEffect.

• SetupChannels This is called when the item type is first defined to determine the channels that should be added to the item definition.

• LinkChannels This is called with an ILxEvaluation interface and the texture should add any channels that it wants to read.

• ReadChannels This is called with an ILxAttributes interface so the texture can read any of the values that it needs at the current time. The values read should be cached (along with any other needed scratch space) to an allocated block of data returned indirectly.

• Customize After channels are read the value texture can request surface features and sample vector packets. No guarantees.

• MaterialEvaluate This is called during rendering for every sample where the material applies.

• ShaderEvaluate This is called during rendering for every sample where the material applies. The function gets the raycast object and the shade component and output packets that it can alter.

• SetShadeFlags This is called before rendering and allows a component shader to set the shading flags, which allows it do things like be transparent to shadow rays or be double sided, or set a light linking group.

• SetBump This is called before rendering and allows a component shader to set its own bump amplitude, so it is evaluate for bump mapping.

• SetDisplacement This works like set bump, but for displacement height.

• SetOpaque This allows the shader to override its “opaqueness”. For shaders that use other shaders as inputs, such as the cel and halftone shader, it is necessary that they are not opaque.

• SetSmoothing This allows the shader to set its material smoothing amount, angle.

• CustomPacket This allows the shader to specify a custom packet it SETS.

• Cleanup Frees the data block allocated by ReadChannels() method.

• UpdatePreview This allows the shader to specify the update flags it might trigger for Preview.
