IGES at a glance
IGES
Convert to IGES when the receiving engineering system or supplier workflow still expects that neutral geometry format, particularly for curves and surface-focused CAD exchange.
It is useful for legacy interoperability and long-lived manufacturing relationships.
For newer product-model exchange with richer semantics, STEP is often the better choice.
GLSL Mesh at a glance
GLSL Mesh
Convert to GLSL-Mesh when a rendering pipeline needs bundled geometry plus shader source for demos, research scenes, or custom real-time engines.
It is most useful where reproducing a specific GPU shading setup matters as much as transferring the mesh itself.

When to use each format
When to use IGES
- design authoring
- review handoff
- manufacturing exchange
- Historically significant neutral CAD exchange format.
When to use GLSL Mesh
- design authoring
- review handoff
- manufacturing exchange
- Closely aligned with classic OpenGL programmable-pipeline workflows.
FAQs
Why convert IGES to GLSL Mesh?
Convert to GLSL-Mesh when a rendering pipeline needs bundled geometry plus shader source for demos, research scenes, or custom real-time engines.
It is most useful where reproducing a specific GPU shading setup matters as much as transferring the mesh itself.
What changes when converting IGES to GLSL Mesh?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting IGES to GLSL Mesh?
Check the exported file for GLSL itself is a shading language, not a full mesh interchange container.; Not suitable as a broad CAD or scene-exchange target for contemporary pipelines..
