NGRAIN Write Options
Facet Generation Options
Max Normal Deviation - Every facet position (x,y,z), also called a node, rests exactly on the surface of a part. At every facet node a surface normal can be created. Normal Deviation specifies that at every facet-node-surface-normal the maximum deviation angle in degrees between any other facet-node-surface-normal can not exceed this degree value.
Maximum Surface Deviation - Maximum Surface Deviation specifies a value based on the application units specified under the File->Settings dialog and General tab. This value is the maximum perpendicular distance from the center (centroid) of any facet to where this perpendicular ray intersects with the true surface of the part.
Voxel Generation Options
Voxel Cube Size - The default of 500 is means the VSpace (Voxel Space) has a dimension of 500x500x500 Units – an over-all Voxel Space resolution – think of this as an overall bitmap resolution only in 3 dimensions. A larger value = higher quality, a smaller value = lower quality. The maximum value is 4096 Units.
Voxel Oversampling - This option allows you to set the level of oversampling. Oversampling is a quality setting during the conversion process that involves scaling the resolution of the model upwards by a specified factor to determine more accurate settings of which voxels are occupied, what their color values are, and what their normal value is when the model is scaled back down to its intended size. The range of values for this setting is 1 to 7.
Unidirectional Normals - This toggle allows you to choose whether or not you want the converted model to be compatible with applications based on all versions of NGRAIN Constructor (default) or with 3.1 and later versions only. One reason you may want to check this option is if the NGRAIN file you are creating will be used in an application that utilizes NGRAIN Constructor's collision detection feature (3.1 or later).
Voxel Overlap Handling - This toggle allows you to choose whether or not you want the conversion process to handle voxel overlapping. If set to checked, this option allows close proximity model parts to occupy separate voxels and maintain the correct information. This is helpful when dealing with assemblies and moving parts. If checked you will not see the voxel “holes” when one close part is moved away from another one.
Download Mobilizer Viewer - This button will launch your browser and navigate to the download page for the NGRAIN Mobilizer Viewer. NGRAIN’s free viewer, Mobilizer, operates within HTML pages, Microsoft Word documents, and other materials to deliver unsurpassed real-time interactivity with 3D Knowledge Objects (3KO Files), on common desktop, laptop, and Tablet computers.
NGRAIN Write Format
3KO - The 3KO format is NGRAIN's default format for their applications that make use of the Knowldedge Object features of this format. The 3KO format is an NGW Voxel Space format with additional meta data such as part knowledge.

NGW - The NGW format is NGRAIN's core Voxel Space format. Though it is rarely used you can create this format for the purposes of interoperating with legacy NGRAIN based applications.
