Hi sir:
I refer to GLScene demo - Samples\Delphi\Demos\graph\points, make a prog. I wanted to achieve was to show a tube with a section of 32,000 points and a tube with 900 sections. The diameter of the tube is 20cm, and the length is 15m. I can observe the tube and its details through the operation of the mouse or keyboard, but find many problems.
1, image anamorphosis is very serious, and I feels that the angle of view is too large?
2, some of the images will disappear during the Zoom operate.
3, can not be flexibly zooming, rotating and moving.
4, can it be stored in other model formats, such as 3DS and so on.
5, compile to 32 bit program, always error: memory overflow.
1) the best for what you want to do is in samples\delphi\demos\extrusion\tentacles
2) You need adjust Camera NearPlaneBias property
3) Don(t understand Camera ? or Object ?
4) Yes it can but the model will be statics, you can use GLScene's SaveToFile, SaveToString, SavetoTextFile fore saving the whole scene. For export you need you GLFeedBack (see in samples) for transforming scene to GLFreeForm and save it after
5) It is the same with 64 bits ? This error is due because you don't have enought RAM free
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
1) I just want to display a lot of points ,and can zoom , pan and rotation
2) I have adjusted GLSceneViewer1.camera.NearPlaneBias, I think it is cut view by distance?
3) I could understand them ,but I can not use them in GLScene very well.
4) I am tring..
5) I have 16GB ram, win 10 64Bit, I only used 23%. Why?
Thanks

Hi
At first Thanks for your reply .
1) I just want to display a lot of points ,and can zoom , pan and rotation
2) I have adjusted GLSceneViewer1.camera.NearPlaneBias, I think it is cut view by distance?
3) I could understand them ,but I can not use them in GLScene very well.
4) I am tring..
5) I have 16GB ram, win 10 64Bit, I only used 23%. Why?

Hi
take a look to at this topic : https://sourceforge.net/p/glscene/discussion/93606/thread/a5922617/
Now for memory i can't answer i must have a sample to see what the problem exactly
If you have a little sample i'll could convert to Lazarus or i'll could try with Delphi community Edition it will be welcome
