panda3d.core.LightLensNode¶

from panda3d.core import LightLensNode

class LightLensNode¶

Bases: Light, Camera

A derivative of Light and of Camera. The name might be misleading: it does not directly derive from LensNode, but through the Camera class. The Camera serves no purpose unless shadows are enabled.

Inheritance diagram

static getClassType() → TypeHandle¶

Return type: TypeHandle

getShadowBuffer(gsg: GraphicsStateGuardianBase) → GraphicsOutputBase¶

Returns the buffer that has been constructed for a given GSG, or NULL if no such buffer has (yet) been constructed. This should be used for debugging only, you will not need to call this normally.

Return type: GraphicsOutputBase

getShadowBufferSize() → LVecBase2i¶

Returns the size of the shadow buffer to be created for this light source.

Return type: LVecBase2i

getShadowBufferSort() → int¶: Returns the sort of the shadow buffer to be created for this light source.

hasSpecularColor() → bool¶: Returns true if this light defines a specular color, false if the specular color is derived automatically from the light color.

isShadowCaster() → bool¶: Returns whether this light is configured to cast shadows or not.

output(out: ostream) → None¶: We have to explicitly publish these because they resolve the multiple inheritance.

setShadowBufferSize(size: LVecBase2i) → None¶: Sets the size of the shadow buffer to be created for this light source.

setShadowCaster(caster: bool) → None¶: Sets the flag indicating whether this light should cast shadows or not. This is the variant without buffer size, meaning that the current buffer size will be kept (512x512 is the default). Note that enabling shadows will require the shader generator to be enabled on the scene.

setShadowCaster(caster: bool, buffer_xsize: int, buffer_ysize: int, sort: int) → None: Sets the flag indicating whether this light should cast shadows or not. The xsize and ysize parameters specify the size of the shadow buffer that will be set up, the sort parameter specifies the sort. Note that enabling shadows will require the shader generator to be enabled on the scene.

property shadow_buffer_size¶

Getter: Returns the size of the shadow buffer to be created for this light source.
Setter: Sets the size of the shadow buffer to be created for this light source.

Return type: LVecBase2i

property shadow_caster¶

Returns whether this light is configured to cast shadows or not.

Return type: bool

write(out: ostream, indent_level: int) → None¶
