Shadow Camera Settings

Shadow Camera Settings

SETTING

DESCRIPTION

Width/Height/Depth

Configures the extent to which shadows are displayed.

Offset X/Y/Z

The Shadow Camera's default center view can be adjusted to have an offset on all axes.

Bias

This value is essential for resolving various shadow-related issues, such as peter-panning or shadow acne. The required size of this value varies depending on the dimensions of the shadow camera.

SETTING

DESCRIPTION

Environment texture URL

Use your own environment map hosted on an external server by inputting the corresponding image URL. Alternatively, select from one of the default environment maps provided by TwikBot 5, which are accessible in Settings | Environment maps.

Pitch/Yaw/Roll

These settings enable you to define the range within which the camera can orbit around the origin. You can also set initial values to specify the camera angle upon the scene's first load. This initial value must fall within the minimum and maximum values.

Note: The initial value must be set within the defined minimum and maximum range values.

Auto zoom

The Auto zoom feature dynamically adjusts the camera's zoom to fit the object within its bounding box. This ensures a consistent distance from the object, regardless of its scale. Note: Disabling Auto zoom fixes the camera's position, which requires careful input values to prevent the camera from clipping through the object

Min zoom/Max zoom/initial zoom

The zoom settings include a minimum value, maximum value, and an initial zoom point.

Note: When a new product is created, these options are disabled by default.

Near/Far/Field of view

Near: This value specifies the camera's closest clipping point in the scene. A smaller value allows the camera to zoom in closer without clipping through objects.

Far: This value specifies the camera's farthest clipping point in the scene. A larger value allows the camera to zoom out further without clipping away any part of the scene.

Field of view: This setting defines the focal length of a camera lens. A higher value results in a wider view, while a lower value results in a narrower view.

Offset X/Y/Z

While the camera focuses on the scene's origin point (0,0,0) by default, the offset options allow the user to adjust this focal point.

Tone mapping

Tone-mapping

SETTING

DESCRIPTION

Tone-Mapping

This is used to approximate the appearance of high dynamic range (HDR) on the low dynamic range medium of a standard computer monitor or mobile device's screen.

Tone-Mapping: Method

Available tone mapping methods:

  • Linear

  • Reinhard

  • Uncharted 2

  • Cineon

Tone-Mapping: Exposure

Exposure level of tone mapping. Default is 1

Tone-Mapping: White-Point

White-Point value of tone mapping. Default is 1

Bloom

Bloom

SETTING

DESCRIPTION

Bloom

Bloom effects can be applied to enhance the lighting effects on an object within the scene. This effect creates fringes or 'feathers' of light arising from the edges of bright areas on an object, simulating the appearance of an intensely bright light that overwhelms the camera.

Bloom: Strength/Radius/Threshold

Strength: This setting adjusts the intensity of the bloom effect, particularly focusing on the quantity of light reflecting off the object.

Radius: Specifies the distance between the origin and the furthest edge of the light, affecting the bloom's feathering effect.

Threshold: This setting determines the width of the feathering effect created by the radius.

New Ambient Occlusion

New Ambient Occlusion

SETTING

DESCRIPTION

Ambient Occlusion

This shadowing method enhances the visual quality of 3D objects by replicating the soft shadows that naturally arise from indirect or ambient lighting.

Kernel Radius/Min Distance/Max Distance

Kernel Radius: Sets the radius for the shadow simulation, influencing the extent of the shadow effect.

Min Distance: Specifies the minimum distance required between the object and the ambient occlusion, defining the shadow's start point.

Max Distance: Establishes the maximum distance between the object and the ambient occlusion, determining how far the shadow effect can extend.

Anti-aliasing

Anti-aliasing

Supersampling factor

Anti-aliasing is applied in computer graphics to eliminate the aliasing effect, characterized by jagged edges in digital images.

The supersampling factor determines the extent to which aliasing is reduced.

Disable blur

Disables blur effects

UI controls

UI Controls

Desktop/Mobile zoom

Desktop users can zoom in two ways: using the mouse scroll wheel or by pressing Ctrl in combination with the mouse scroll wheel. On mobile devices, the zoom functionality is exclusively available through a pinch gesture.

Disable zoom

Activates or deactivates the zoom function.

Desktop/Mobile rotation

On desktop, rotation is achieved by holding the left mouse button and moving the mouse. For mobile devices, rotation can be set to either a one-finger or two-finger gesture for manipulating the visualization.

Edit Three Scene/Remove Three Scene

You have the option to configure your 3D scene, including aspects like light sources and shadows, using the three.js editor. (https://threejs.org/editor/)

Once you have configured the scene in three.js, export the scene. The resulting Json data can then be imported into the graph editor by selecting the 'Edit Three Scene' option."

It is recommended to exclude 3D geometries from the Json data and focus solely on light sources and shadow configurations.

Remove custom Camera settings

This action resets all custom settings, reverting the camera and scene back to their default configurations.
