Some Mesh Textures Invisible on Contour Map

Anonymous — Thu, 25 May 2023 14:58:09 GMT

I've been working on a large contour map around 4000'x3000' at 1' intervals and ran into a few texture glitches. In the mesh model there are invisible polygon textures along the contours that remain after refreshing the viewpoint. I'm using OpenGL as my engine.

Is there any way to correct these glitches through settings manipulation or other viewing options?

I'm running ArchiCAD 18 build 5100.

You could try to convert the Mesh to a Morph and see if that helps any.

I tried converting the model to a morph, it fixes some texture issues but others form in different places. I need to keep this model as a mesh for this project,

Looking at your image I am wondering if there are a lot of surface nodes that aren't actually on the top surface?

Cut a small section through the white area with a marquee or even a section line and have a close look to see if the nodes are all at the top surface level.

Take a copy of your mesh and cut it into small sections with the split tool to see if that makes any difference.
Maybe smaller meshes will be better than one big one.

I started working on a new mesh using a different method.
My process is:
-Gather google earth 3d imagery in Sketchup
-Start project in Archicad
-Place 3d cutting plane at contour height 1' intervals
-Marquee and copy cutting plane outline to new layer
-Create spline from cutting plane outline 10' intervals
-Create mesh level from spline

The model is looking better without my own height errors, but I'm still getting the texture issue in similar locations on the new model.
