Realistic Rendering

Use a ray tracing renderer to achieve realistic rendering effects.

Configuration Requirements: Realistic rendering requires high computer configuration. It is recommended to use a high-spec computer to run this function.

• Low-spec graphics card (VRAM under 4GB) limit: 200,000 faces;
• Mid-spec graphics card (VRAM 4-8GB) limit: 10 million faces;
• High-spec graphics card (VRAM over 8GB) limit: 15 million faces.

Note: In System Settings, you can adjust the current device configuration to enable larger models.

Usage:

1. Open the model to be rendered, set "Appearance, Light Source, Scene".
2. Click the "Ray Tracing Renderer" command to enter ray tracing rendering mode.
3. Click the "Ray Tracing Renderer Parameters" command to adjust rendering parameters.
4. Keep the model stationary and wait for the scene to render.
5. Click the Save Image button to download the rendered scene to the local device.
6. Click the "Exit Ray Tracing Renderer" command to exit ray tracing rendering mode.

Dialog Box Control Descriptions:

• Scene
  • Environment Light Rotation: Rotates the environment map in space, changing its orientation, which affects the lighting direction and shadow distribution of objects in the scene.
  • Denoise: Processes rendered output images or video frames to eliminate chaotic pixels (i.e., "noise") caused by ray tracing, insufficient sampling, or noise interference, resulting in a cleaner and clearer visual effect. This option is unavailable when the browser does not support WebGPU.
  • Denoise Sampling: Performs denoising on a specific frame image in the video to improve the visual quality of that frame.
  • Super Resolution: Reconstructs low-resolution images into high-resolution images through algorithms, visually enhancing details,clarity, and realism without actually rendering higher-resolution pixels.This option is unavailable when the browser does not support WebGPU.
  • Super Resolution Multiplier: Represents the enhancement level of super resolution processing.
• Renderer
  • Maximum Bounces: Used to control the maximum number of times light reflects or refracts in the scene.
  • Tile Count: Used to improve rendering performance and memory efficiency.
  • Specular Filter: Determines which pixels or data values will be "clamped" to a specified upper or lower limit to prevent numerical overflow or anomalies.
• Display
  • Exposure: A parameter that controls the overall brightness of the scene, determining whether the scene looks too bright,too dark, or normally exposed in the final output.
  • Tone Mapping: A key step in converting High Dynamic Range (HDR) images (such as real lighting calculation results) to Low Dynamic Range (LDR) images (such as the 0~1 color range displayable by monitors),used to simulate the human eye's adaptation process to light, ensuring the scene is neither overexposed nor underexposed, maintaining visual realism.
  • Gamma Correction: Used to compensate for the non-linear brightness response characteristics of display devices, ensuring consistent brightness display across different screens, avoiding scenes that are too dark or too bright.
  • Anti-Aliasing: After rendering is complete, blurs the edges of the image to visually reduce the jagged effect.
  • Render Resolution: The pixel size of the final output image,i.e., the width and height of the rendering result (e.g., 1920×1080,3840×2160, etc.).
  • Navigation Resolution: The lower-resolution temporary image used by the renderer during scene navigation (such as rotating, panning, zooming the camera) to achieve smooth real-time interaction.
  • Path Tracing Navigation: Simulates the propagation path of real light in the scene (reflection, refraction,shadows, etc.) to achieve accurate identification and interaction response of object positions, surface properties, and spatial relationships, thereby providing a more realistic and intuitive navigation experience.
• Background
  • Show Environment: Controls whether to display the environment.
  • Background Color: Sets the background color.
• Save Image: Click to save the current rendering effect to the local device.
