Depending on the light source, SpinFire Ultimate will determine whether or not a pixel is in shadow and store this information as a numerical value in a shadow map. The resulting shadows have jagged edges. In order to smooth the edges, random samples of values stored in the shadow map are averaged, which produces a shadow factor that can be used to smooth the border between light and shadow.

Enable Shadow Map - The Shadow Map render effect is used as when loading a model.

Samples - The greater the number of samples, the smoother the shadow edges, but the scene will take longer to render.

Values are 2, 4, 8, 16, 32, 64, 128, 256.

Resolution - The accuracy of the shadow map is limited by its resolution. Greater resolution uses more memory and can take longer to generate.

Values are 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288.

View Dependence - When enabled, the view is scaled and refreshed with the camera, ensuring consistent visuals in 3D View.

Jitter - When jitter is enabled, a randomizing function is applied to the process of determining where to take shadow map samples. Jitter may improve a scene visually by softening jagged shadow edges.

Creates a reflection of the model.

Enable Simple Reflection - The Simple Refliection render effect is used as when loading a model.

Opacity - The degree of non-transparency.

Blurring - The degree to which the reflection edges are blurred.

Fading - An gradient effect causing the reflection to appear as though it fades into the background.

Attenuation Near Distance - The distance between the light source and the model where the reflection begins to fade.

Attenuation Far Distance - The distance between light source and the model where the reflection is completely faded.

Graphics Driver - Select a graphics driver from the drop-down list. SpinFire Ultimate supports OpenGL, OpenGL 2, OpenGL 2 Mesa, and DirectX 11.

Frame Rate Enabled - Use the Frame Rate field when checked.

Frame Rate - The number of frames of an animation displayed every second. The higher the frame rate, the smoother the animationwill appear, but processing power and system bandwidth requirements increase as well.

Values are 0 to 30.

Anti-Aliasing - By default, SpinFire Ultimate will smooth out any jagged diagonal or curved lines. Also known as dithering. Clear the checkbox to disable.

Anti-Aliasing Level - Set anti-aliasing to either 2, 4, or 8. The default is 4.

Rendering Mode - Wireframe, Hidden Lines Removed, Triangle Mesh, Flat Shaded, Smooth Shaded, Smooth with Edges, Reflective, Metallic, Surface Analysis.

Culling Enabled - Enables culling when set. Used with the Culling Level setting.

Culling Level - This is the size in pixels which objects are drawn. Smaller the objects drawn with larger the culling levels may be reduced to not appearing on screen. Larger culling levels may improve drawing performance.

Default value: 20.

Depth Peeling Enabled - Enables depth peeling when set. Used with the Depth Peeling Layers setting.

Depth Peeling Layers - Indicates the number of layers of overlapping transparency used when drawing objects. The smaller the value, the better the performance.

Default value: 5. 

Static Model Enabled - Enable to boost performance with pan/zoom/rotate. Usage may negatively effect other functionality.

Front Facing PMI - Enable to have PMI text always front facing despite flipping and rotating of the model.

Front Rendered PMI - Enable for PMI to always be in front.

Animated between views Enabled - When enabled, transitioning to a User view is smoothly animated.

Animation Speed - Select 1 of 6 different speeds to animated User view transitions.

Display Grid - When enabled, Front, Back, Top, Bottom, Right, or Left standard views include a background grid.

Camera Projection - Determines how objects are viewed. In perspective mode, grid lines converge to a vanishing point. This provides the illusion of depth in the viewport; objects farther away look smaller. In parallel mode, all the grid lines are parallel to each other, and identical objects look the same size, regardless of where they are in the view.

Values are Perspective Mode, Parallel Mode.

Projection - Determines the orthogonal projection method used when the model is displayed in 4 Viewport and 3+1 viewport modes.

Values are 1st Angle (4 Viewport: Left , Top, front, isometric; 3+1 Viewport: Bottom, Front, Top, lg isometric) 3rd Angle (4 Viewport: Right, Bottom, Front, isometric; 3+1 Viewport: Top, Front, Bottom, lg isometric).

Axis Triad Enabled - Specifies whether or not the coordinate system triad (frame) is displayed in the scene.

Axis Triad Location - Specifies where in the scene the coordinated system triad is located.

Values are Top Right, Top Left, Bottom Right, Bottom Left.

Navigation Cube Enabled - Specifies whether or not the navigation cube (point-of-view quick reference) is displayed in the scene.

Navigation Cube Location - Specifies where in the scene the navigation cube is located.

Values are Top Right, Top Left, Bottom Right, Bottom Left.

Font - Click the Font name (default is Microsoft Sans Serif 12 pt) to select font, font style, size, effects, and color for markup and measurement labels.

Background - Click the Color... button to select the background color for markup and measurement labels.

Image Added

Specifies SpinFire Ultimate ACT3D file export characteristics.

B-Rep Compression - Set the level of boundary representation (B-Rep) data compression.

Values are: None, Low, Medium, High.

Include B-Rep - When enabled, B-Rep information is preserved when file is saved. The B-Rep provides greater accuracy when measuring volumes and curved surfaces, but increases file size.

Tessellation Compression - When enabled, tessellation is compressed when the file is saved, which results in a smaller file size (but accuracy is diminished).

3D Preview - When enabled, 3D preview data is included when the file is saved.
