Display in the Figure Window

Display Mode(at the top right corner of each viewport) > GPU Ray Tracing

This is enabled when the Display Mode is set to any of Shading, Shading and Wireframe, Texture or Texture and Wireframe.

By switching to GPU Ray Tracing, the rendering results can now be checked in the Figure Window in real time.

The following features are supported compared to the Phong display mode

Phong	GPU Ray Tracing

• AI Denoiser (Intel Open Image Denoise)
• Reflection of an object by specular reflection
• Transparency、Refraction
• Available only for Shade3D material
Transparent Alpha for image Mapping (for billboard rendering)
• Available only for PBR material
Specular and Transparency adjustment of image Mapping
Indirect illumination expression by global illumination

Options

AI Denoiser

Intel Open Image Denoise

Remove high frequency noise with AI deep learning based filter.

Sampling

Ray Cast Level

The number of times of ray reflection. Rendering time will increase if rendering is performed for reflections that are repeated a large number of times.
To avoid this, Shade3D can place restrictions on the number of times of reflection. No reflection occurs exceeding the specified value.

Sample Count

Adjust the ray tracing quality. Image quality improves and rendering time increases in proportion to the value.

Reflection Factor

Specify the ratio at which the indirect radiation affects the global illumination.
When the value is smaller, then the calculation speed improves, but the effect of global illumination will become weaker.

Rendering Settings

Method > GPU Ray Tracing

Render with GPU ray tracing.

The rendering process is not shown as in other methods, only the resulting image is displayed.

Parameter Settings

Tab	Items	Description
Basics	Intel Open Image Denoise	・Perform noise reduction. ・Normal pass and Surface material: albedo pass will not be generated.
	Antialiasing	・Same as other rendering methods. When selected, anti-aliasing is performed during rendering.
	Render Background	・Turn Render Background and Reflect Background on and off as a set.
	Illuminance Correction	・Same as other rendering methods. The intensity of all lights in the scene can be adjusted at once to correct the brightness of the scene.
	Render Shadows	・Same as other rendering methods. Shadows of objects are rendered.
Image	Color Management	・Same as other rendering methods. See also Linear Workflow
	Resolution	・Same as other rendering methods. Specifies the resolution of the image to be rendered with DPI.
G.I.	Reflection Factor	・Same as other rendering methods. Specify the ratio at which the indirect radiation affects the global illumination.
Effects	Effector	・The following effectors are available. Add Noise, Invert Color, BlurEffector, Burn Timecode, Burn Rendering Info
Misc.	Compatibility	・Invalid
	Ray Cast Level	・Same as other rendering methods. The number of times of ray reflection.
	Sample Count	・Adjust the quality of the ray tracing. ・Image quality improves and rendering time increases in proportion to the value.
