TextureEffectPlay_Looping 

Video starts playing as soon as possible.

Definition at line 59 of file OgreExternalTextureSource.h.

Enumeration of the types of constant we may encounter in programs.

Note
Low-level programs, by definition, will always use either float4 or int4 constant types since that is the fundamental underlying type in assembler.

The variability of a GPU parameter, as derived from auto-params targetting it.

These values must be powers of two since they are used in masks.

Enumerator
GPV_GLOBAL 

No variation except by manual setting - the default.

GPV_PER_OBJECT 

Varies per object (based on an auto param usually), but not per light setup.

GPV_LIGHTS 

Varies with light setup.

GPV_PASS_ITERATION_NUMBER 

Varies with pass iteration number.

GPV_ALL 

Full mask (16-bit)

Definition at line 83 of file OgreGpuProgramParams.h.

Part of the rendering which occurs per light.

IS_DECAL 

Post-lighting rendering.

IS_UNKNOWN 

Not determined.

Definition at line 49 of file OgrePass.h.

List of valid texture blending operations, for use with TextureUnitState::setColourOperation.

Remarks
This list is a more limited list than LayerBlendOperationEx because it only includes operations that are supportable in both multipass and multitexture rendering and thus provides automatic fallback if multitexture hardware is lacking or insufficient.
Enumerator
LBO_REPLACE 

Replace all colour with texture with no adjustment.

LBO_ADD 

Add colour components together.

LBO_MODULATE 

Multiply colour components together.

LBO_ALPHA_BLEND 

Blend based on texture alpha.

Definition at line 57 of file OgreBlendMode.h.

Expert list of valid texture blending operations, for use with TextureUnitState::setColourOperationEx and TextureUnitState::setAlphaOperation, and internally in the LayerBlendModeEx class.

It's worth noting that these operations are for blending between texture layers and not between rendered objects and the existing scene. Because all of these modes are only supported in multitexture hardware it may be required to set up a fallback operation where this hardware is not available.

Enumerator
LBX_SOURCE1 

use source1 without modification

LBX_SOURCE2 

use source2 without modification

LBX_MODULATE 

multiply source1 and source2 together

LBX_MODULATE_X2 

as LBX_MODULATE but brighten afterwards (x2)

LBX_MODULATE_X4 

as LBX_MODULATE but brighten more afterwards (x4)

LBX_ADD 

add source1 and source2 together

LBX_ADD_SIGNED 

as LBX_ADD, but subtract 0.5 from the result

LBX_ADD_SMOOTH 

as LBX_ADD, but subtract product from the sum

LBX_SUBTRACT 

subtract source2 from source1

LBX_BLEND_DIFFUSE_ALPHA 

use interpolated alpha value from vertices to scale source1, then add source2 scaled by (1-alpha)

LBX_BLEND_TEXTURE_ALPHA 

as LBX_BLEND_DIFFUSE_ALPHA, but use alpha from texture

LBX_BLEND_CURRENT_ALPHA 

as LBX_BLEND_DIFFUSE_ALPHA, but use current alpha from previous stages

LBX_BLEND_MANUAL 

as LBX_BLEND_DIFFUSE_ALPHA but use a constant manual blend value (0.0-1.0)

LBX_DOTPRODUCT 

dot product of color1 and color2

LBX_BLEND_DIFFUSE_COLOUR 

use interpolated color values from vertices to scale source1, then add source2 scaled by (1-color)

Definition at line 75 of file OgreBlendMode.h.

List of valid sources of values for blending operations used in TextureUnitState::setColourOperation and TextureUnitState::setAlphaOperation, and internally in the LayerBlendModeEx class.

Enumerator

LBS_TEXTURE 

the colour derived from the texture assigned to this layer

Definition at line 47 of file OgreMaterialSerializer.h.

Blending factors for manually blending objects with the scene.

If there isn't a predefined SceneBlendType that you like, then you can specify the blending factors directly to affect the combination of object and the existing scene. See Material::setSceneBlending for more details.

Enumerator
SBF_ONE 
SBF_ZERO 
SBF_DEST_COLOUR

SBF_ONE_MINUS_DEST_ALPHA 
SBF_ONE_MINUS_SOURCE_ALPHA 

Definition at line 234 of file OgreBlendMode.h.

Blending operations controls how objects are blended into the scene.

The default operation is add (+) but by changing this you can change how drawn objects are blended into the existing scene.

Enumerator
SBO_ADD 
SBO_SUBTRACT 
SBO_REVERSE_SUBTRACT 
SBO_MIN 
SBO_MAX 

Definition at line 253 of file OgreBlendMode.h.

Types of blending that you can specify between an object and the existing contents of the scene.

Remarks
As opposed to the LayerBlendType, which classifies blends between texture layers, these blending types blend between the output of the texture units and the pixels already in the viewport, allowing for object transparency, glows, etc.
These types are provided to give quick and easy access to common effects. You can also use the more manual method of supplying source and destination blending factors. See Material::setSceneBlending for more details.

Enumerator
SBT_TRANSPARENT_ALPHA 

Make the object transparent based on the final alpha values in the texture.

SBT_TRANSPARENT_COLOUR 

Make the object transparent based on the colour values in the texture (brighter = more opaque)

SBT_ADD 

Add the texture values to the existing scene content.

SBT_MODULATE 

Multiply the 2 colours together.

SBT_REPLACE 

The default blend mode where source replaces destination.
