DSK “Low Level API”
The calling sequence into the API would typically be as below.
| API | |
|---|---|
dasopr |
Open the DSK kernel. |
dlabfs |
Search for the first segment record. |
dskz02 |
Determine how many vertices and indices. |
dskv02 |
Get the vertex data. |
dskp02 |
Get the indices/triangle data. |
dskn02 |
For each vertex, calculate a surface normal. |
dascls |
Close the DSK kernel. |
dskv02 and dskp02 read arrays of Vertices and “Plates”

3 key Blueprint actions
dskv02
dskv02
Abstract
Fetch vertices from a type 2 DSK segment.
dskp02
dskp02
Abstract
Fetch triangular plates from a type 2 DSK segment.
dskn02
dskn02
Abstract
Compute the unit normal vector for a specified plate from a type 2 DSK segment.
Example
phobos512.bds
3 million vertices
4.5 million indices
1.5 million triangles
This will trigger Unreal Engine’s maximum iteration safeguard. The user must increase the maximum allowable iterations in the project’s settings or distribute the iterations across multiple invocations.
Clearly, a more targetted method would be useful when working with DSK data as Mesh Data.
