VR Object Editor
Access: Editors menu > Snapshot VR Object |
The VR Object Editor produces a 3D image of the product. In this 3D image, the camera is stationary. The object is posed on a plane that turns at regular intervals of time. This allows you to view the object from every angle, with the ability to examine every detail.
Once the desired settings have been indicated, the Render button initiates the creation of the image files that constitute the VR object.
Tip
During rendering, a dialogue box is displayed to show the progression of the creation of the VR object files. At any time, you can pause the progression by clicking the Pause button, or cancel it by clicking on the Cancel button. If you have paused the rendering, start it again by clicking on Resume.
The Viewer button at the bottom of this dialog box opens a window for viewing captures.
Dimensions Zone
The dimensions of the animation to be rendered are filled out in the Dimensions box.
The Format drop-down lists the most common sizes and formats. Some, such as User-Defined, allow you to directly set the dimension values. By default, the format Defined by Viewport is proposed.
Files Zone
The Files zone contains the controls for creating a VR Object.
In this zone you can set:
The output directory where the image file will be saved, as well as the name of the file and its extension,
Whether to Open File Selector or not when rendering. When Open File Selector is selected, clicking on the Render button will show the dialogue box offering the choice of file name and type. This option is selected by default.
Tip
VR objects are saved in the Snapshots directory by default.
To change the format of the file to be created, change the extension of the file name. The following file formats are supported for image output:
.jpg
.png
.bmp
.tif
.exr
.hdr
.psd
Whether to Confirm Overwrite or not when rendering. When Confirm Overwrite is selected, if a file with an identical name is detected, a confirmation will be asked before replacing it with the file being created. This option is selected by default.
The configuration of the compression. Slide the Image compression for VR Objects and Cubic VR Panoramas to define the compression. A higher value will yield a better quality.
Rendering Engine Window
The Configure button in the Rendering Engine zone opens the OpenGL Parameters window.
Choose whether or not to apply:
Antialiasing,
mipmaps,
Mirror Reflections,
Transparent Background.
Choose the level of Super Sampling from the drop-down list.
Use the slider to define the level of Specular Anisotropic Filtering.
Click on OK to save your changes.
Snapshot Zone
If ticked, the Viewer checkbox in the same zone sets the image viewing window to open automatically during rendering.
Internal Render Info Zone
The Internal Render Info zone summarizes various settings. The applicable elements from among following information are displayed:
Width of the image in pixels,
Height of the image in pixels,
The number of Frames to render,
Pass, the number of passes to render the image,
Sampling,
Memory.
Preview Frame Zone
The Preview Frame zone allows you to preview each frame of the camera’s path around the object by moving the slider along the bar.
This preview allows you to check the point of observation. By default, the product is observed with a very large field of view. You can modify the point of observation at any time, either in the active viewport or with the tools in the Camera Path zone. To apply a modification to the point of observation, click the Acquire button in the Camera Path zone.
Camera Path Zone
The Camera Path Zone defines the camera’s position and its path.
To create a VR object, a series of images is generated, in which each image is taken from a point on a circle around a central point. Center values are used to position this central point relative to the origin of the coordinate system. The Radius value establishes the distance between the camera and this central point.
The value FovY in degrees provides the vertical field of view.
If you have made changes, click on the Acquire button in order to validate and apply these settings.
VR Object Settings
The VR object settings establish:
Setting | Description |
|---|---|
Pan Range | Frames can be created either for a complete circle on a horizontal plane (the checkbox Complete Loop is ticked by default) or for a limited arc only. In this latter case, you must supply the angles between which your product will be observed. |
Tilt Range | Frames can be created to form a circle on a horizontal plane around the camera path’s central point or to form a sphere or portion of a sphere around this same point. In these latter cases, you must supply the angles between which your product can be viewed. By default, the camera angles cover a full sphere. The viewing angles range from -90 degrees (the negative Y axis) to +90 degrees (the positive Y axis). |
Number of Frames | Frames can be created closer together or farther apart along the camera path. Pan provides the number of frames along the circle on the horizontal plane. Tilt provides the number of frames between the top and bottom angles, if you have defined a vertical plane. |
