Overview
TextureProjectorParallel is similar to a light that projects a texture into the scene, illuminating geometry that intersects the parallel projection volume.
The TextureProjectorParallel node belongs to the TextureProjector component and its default container field is children. It is available from X3D version 4.0 or higher.

Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.
Hint
SFString [in, out] description “”
Author-provided prose that describes intended purpose of the url asset.
Hint
- Many XML tools substitute XML character references for special characters automatically if needed within an attribute value (such as & for & ampersand character, or " for “ quotation-mark character).
SFBool [in, out] global TRUE
Global texture projection illuminates all objects within their volume of influence. Scoped texture projection (global false) only illuminates objects within the same transformation hierarchy.
SFBool [in, out] on TRUE
Enables/disables this texture projection source.
SFColor [in, out] color 1 1 1 [0,1]
color of light, applied to colors of objects.
Hint
SFFloat [in, out] intensity 1 [0,∞)
Brightness of direct emission from the light.
SFFloat [in, out] ambientIntensity 0 [0,1]
Brightness of ambient (nondirectional background) emission from the light. Interchange profile hint: this field may be ignored, applying the default value regardless.
SFVec3f [in, out] location 0 0 0 (-∞,∞)
Position of center of texture projection relative to local coordinate system.
SFVec3f [in, out] direction 0 0 1 (-∞,∞)
Direction for projection.
SFVec3f [in, out] upVector 0 0 1 (-∞,∞)
upVector describes the roll of the camera by saying which direction is up for the camera’s orientation.
MFFloat [in, out] fieldOfView [ -1, -1, 1, 1 ] (-∞,∞)
Minimum and maximum extents of projection texture in units of local coordinate system. Small field of view roughly corresponds to a telephoto lens, large field of view roughly corresponds to a wide-angle lens.
Hint
- Rectangular display width/height = (maxX-minX) / (maxY-minY).
Warnings
- Minimum corner values must remain less than maximum corner values.
- This field differs for TextureProjectorParallel and TextureProjector.
SFFloat [in, out] nearDistance -1 -1 or (0,∞)
Minimum distance necessary for texture display.
SFFloat [in, out] farDistance -1 -1 or (0,∞)
Maximum distance necessary for texture display.
SFFloat [out] aspectRatio
aspectRatio is the ratio of width and height that is projected.
SFNode [in, out] texture NULL [X3DTexture2DNode]
Single contained texture node (ImageTexture, MovieTexture, PixelTexture, MultiTexture) that maps image(s) to surface geometry.
Hints
- If texture node is NULL or unspecified, corresponding Shape geometry for this Appearance is not textured.

SFBool [in, out] shadows FALSE
shadows field indicates whether or not this light casts a shadow behind illuminated X3DShapeNode geometry.
SFColor [in, out] shadowColor 0 0 0 [0,1] non standard
Color of shadow, applied to colors of objects.
SFFloat [in, out] shadowIntensity 1 [0,1]
shadowIntensity field defines how much light is obscured by shapes that cast shadows, ranging from 0 (light not obscured, no visible shadows) to 1 (light completely obscured, full-intensity shadows).
SFFloat [in, out] shadowBias 0.005 [0,1] non standard
The shadowBias value controls the visibility of shadow acne.
SFInt32 [ ] shadowMapSize 1024 [0,∞) non standard
Size of the shadow map in pixels, must be power of two.
Hints
- If texture node is NULL or unspecified, corresponding Shape geometry for this Appearance is not textured.
