Thermal imaging mode

Warning

This feature is experimental and may not work as expected. Please share your feedback with us!

Enable thermal imaging visualization to simulate infrared camera effects, including thermal conductivity of assets, thermal profiles of water bodies, and atmospheric thermal gradients.

Enable thermal imaging mode

world.camera.enable_thermal_mode(True)

The thermal imaging mode applies several effects:

• Distance-based gradient blending of sky temperatures

• Material-based thermal conductivity simulation for assets

• Thermal profile visualization of ocean and water bodies

To render and save thermal images as part of your synthset, use the following command:

Render thermal images

scenario.render(params=RenderParams.RgbWithThermal())

When downloading the synthset, thermal images will be included in the resultant ZIP file with the prefix Thermal_.

Previewing thermal imagery in the gallery

The gallery interface provides a dropdown menu in the top-right corner of each image, allowing you to toggle between RGB and thermal visualization modes:

Thermal Shader Parameters

The thermal shader provides several parameters to customize the thermal visualization. All parameters accept values between 0 and 1, with default values set to 0.5 unless otherwise specified.

Sky Parameters

set_sky_transition_point(value: float)

Controls the vertical position where the sky transitions from visible to dark.

• Default: 0.5

• 0: Sky is completely visible

• 1: Sky blends into horizon with complete darkness

set_sky_temperature(value: float)

Controls the thermal state of the sky.

• Default: 0.5

• 0: Coldest thermal state of the sky

• 1: Warmest thermal state of the sky

Ocean Parameters

set_ocean_min_temperature(value: float)

Sets the minimum thermal state of the ocean.

• Default: 0.3
