Synopsis

$ 3DFileViewer [file]

Description

3D File Viewer is an application for viewing 3D models.

It currently supports opening the Wavefront OBJ file format (.obj).

Features

By default, 3D File Viewer opens with a rotating Utah teapot, a standard 3D test model. Open files via File → Open (Ctrl+O) or dragging and dropping files into the application. Sample files can be found in Documents/3D Models.

Orbit around the model by grabbing it with the cursor, and zoom in and out with the mouse wheel.

View Options

• View in Fullscreen mode by pressing F11 and press Esc to return to windowed mode.
• Rotation Axis - Enable or disable rotation:
  • X rotates upwards.
  • Y rotates right.
  • Z rotates clockwise.
• Rotation Speed - Set to slow, normal, fast or disable.
• Show Frame Rate - Display FPS (frames per second) and frame time values (indicating how long it took to render a single frame) in the top-right corner.

Texture Options

To load a texture, ensure there's a Bitmap image file (.bmp) with the same name as the OBJ file in the same folder and 3D File Viewer will attempt to load it automatically.

• Enable Texture - On by default, disable for a blank (gray) model.
• Wrap S or T - Controls how a texture is applied horizontally (S) or vertically (T):
  • Repeat - Tiles the texture along the axis.
  • Mirrored - Tiles and mirrors the texture along the axis.
  • Clamp - Stretches or clamps the texture edges instead of repeating it.
• Scale - Adjusts texture size (e.g. 0.5 reduces by half, 2x doubles the size).
• Mag Filter - Determines the appearance of textures when enlarged beyond their original resolution.
  • Nearest - Nearest Neighbor means no scaling is applied to the texture, resulting in a pixellated look.
  • Linear - Linear Interpolation scales the image by estimating pixel values, resulting in a smoother image.

Currently, the flashing color lights can't be disabled.

Settings persist whilst the application is open with different files, but do not persist between sessions.

Arguments

• file: The 3D file to be viewed.
