base classes — bpy_struct, ID, Lamp

class bpy.types.AreaLamp(Lamp)

Directional area lamp

compression_threshold

Deep shadow map compression threshold

Type :float in [0, 1], default 0.0

gamma

Light gamma correction value

Type :float in [-inf, inf], default 0.0

ge_shadow_buffer_type

The shadow mapping algorithm used

• SIMPLE Simple, Simple shadow maps.
• VARIANCE Variance, Variance shadow maps.

Type :enum in [‘SIMPLE’, ‘VARIANCE’], default ‘SIMPLE’

shadow_adaptive_threshold

Threshold for Adaptive Sampling (Raytraced shadows)

Type :float in [0, 1], default 0.0

shadow_buffer_bias

Shadow buffer sampling bias

Type :float in [0.001, 5], default 0.0

shadow_buffer_bleed_bias

Bias for reducing light-bleed on variance shadow maps

Type :float in [0, 1], default 0.0

shadow_buffer_clip_end

Shadow map clip end, beyond which objects will not generate shadows

Type :float in [0, 9999], default 0.0

shadow_buffer_clip_start

Shadow map clip start, below which objects will not generate shadows

Type :float in [0, 9999], default 0.0

shadow_buffer_samples

Number of shadow buffer samples

Type :int in [1, 16], default 0

shadow_buffer_size

Resolution of the shadow buffer, higher values give crisper shadows but use more memory

Type :int in [128, 10240], default 0

shadow_buffer_soft

Size of shadow buffer sampling area

Type :float in [0, 100], default 0.0

shadow_buffer_type

Type of shadow buffer

• REGULAR Classical, Classic shadow buffer.
• HALFWAY Classic-Halfway, Regular buffer, averaging the closest and 2nd closest Z value to reducing bias artifacts.
• IRREGULAR Irregular, Irregular buffer produces sharp shadow always, but it doesn’t show up for raytracing.
• DEEP Deep, Deep shadow buffer supports transparency and better filtering, at the cost of more memory usage and processing time.

Type :enum in [‘REGULAR’, ‘HALFWAY’, ‘IRREGULAR’, ‘DEEP’], default ‘REGULAR’

shadow_color

Color of shadows cast by the lamp

Type :float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)

shadow_filter_type

Type of shadow filter (Buffer Shadows)

• BOX Box, Apply the Box filter to shadow buffer samples.
• TENT Tent, Apply the Tent Filter to shadow buffer samples.
• GAUSS Gauss, Apply the Gauss filter to shadow buffer samples.

Type :enum in [‘BOX’, ‘TENT’, ‘GAUSS’], default ‘BOX’

shadow_method

• NOSHADOW No Shadow.
• RAY_SHADOW Ray Shadow, Use ray tracing for shadow.

Type :enum in [‘NOSHADOW’, ‘RAY_SHADOW’], default ‘NOSHADOW’

shadow_ray_sample_method

Method for generating shadow samples: Adaptive QMC is fastest, Constant QMC is less noisy but slower

Type :enum in [‘ADAPTIVE_QMC’, ‘CONSTANT_QMC’, ‘CONSTANT_JITTERED’], default ‘CONSTANT_JITTERED’

shadow_ray_samples_x

Number of samples taken extra (samples x samples)

Type :int in [1, 64], default 0

shadow_ray_samples_y

Number of samples taken extra (samples x samples)

Type :int in [1, 64], default 0

shadow_sample_buffers

Number of shadow buffers to render for better AA, this increases memory usage

• BUFFERS_1 1, Only one buffer rendered.
• BUFFERS_4 4, Render 4 buffers for better AA, this quadruples memory usage.
• BUFFERS_9 9, Render 9 buffers for better AA, this uses nine times more memory.

Type :enum in [‘BUFFERS_1’, ‘BUFFERS_4’, ‘BUFFERS_9’], default ‘BUFFERS_1’

shadow_soft_size

Light size for ray shadow sampling (Raytraced shadows)

Type :float in [0, inf], default 0.0

shape

Shape of the area lamp

Type :enum in [‘SQUARE’, ‘RECTANGLE’], default ‘SQUARE’

size

Size of the area of the area Lamp, X direction size for Rectangle shapes

Type :float in [0, inf], default 0.0

size_y

Size of the area of the area Lamp in the Y direction for Rectangle shapes

Type :float in [0, inf], default 0.0

use_auto_clip_end

Automatic calculation of clipping-end, based on visible vertices

Type :boolean, default False

use_auto_clip_start

Automatic calculation of clipping-start, based on visible vertices

Type :boolean, default False

use_dither

Use 2x2 dithering for sampling (Constant Jittered sampling)

Type :boolean, default False

use_jitter

Use noise for sampling (Constant Jittered sampling)

Type :boolean, default False

use_only_shadow

Cast shadows only, without illuminating objects

Type :boolean, default False

use_shadow

Type :boolean, default False

use_shadow_layer

Objects on the same layers only cast shadows

Type :boolean, default False

use_umbra

Emphasize parts that are fully shadowed (Constant Jittered sampling)

Type :boolean, default False
