Wrong mesh (FreeForm) visualization

[shine world]

Hi all,
I've a problem involved with meshes (TGLFreeFrom) visualization.
This is issue is evidenced at different camera distance.
More is the distance of camera from target more are ugly defects in mesh visualization:

When camera is veri close to object the mesh visualizzation is better.
Have you any suggestion about that ?

Thank you very much!!!
Best regards,

Hi what's you scene's settings
DethOfView (Viewer/Camera) --> min 1000
NearPlaneBias (Viewer/Camera) --> set to min 0.001 to 0.00001
Buffer.DepthPrecision --> Try to set to dp32bits
Buffer.DepthTest --> True
Buffer.FaceCulling --> True
FreeForm or Parent object.ObjectSorting --> try to set to osRenderFarthestFirst
* FreeForm or Parent object..VisibilityCulling --> try set to vcObjectBased or vcHierarchical

you can also try to set in Viewer.Buffer.ContextOptions this param :
* roTwoSideLighting

Your objects seems to be very close to each others so when objects are far, objects rendering can overlapping. This the scratches we can see.

Cheers

These are my at moment settings:

Camera info:
DepthOfView := 100000;
NearPlaneBias := 1;

PS: decreasing NearPlanesBias to 0.001 the issue defects increases.
Using NearPlanesBias to 10 the quality improves a lot.

Buffer.DepthPrecision is set to dpDefaults.
I've got a lot of issues with dp32 bits when OpenGL is running in Intel embedded GPUs.

Buffer.DelpthTest := True;
Buffer.FaceCulling := True;

Seem work on NearPlaneBias is the right way :)
