Sergio, there is no special installer for Lazarus. But it should be installed and work, otherwise fix problems and edit the installation help.

Maybe I understood better now. My doubt is,. When I install GLZscene it can be used with Lazarus ?

I use GLXscene . Where is the installer for GLScene for Lazarus ? I could not find in SourceForge . Can you give me the link

Thanks Pavel, I don't know about the design time problem but for me the problem occurred when reading a 3ds file I saved from Blender years ago. Then, a few months ago the 3ds file could no longer be loaded and I recently located that the problem was the shininess property. There must have been a change in the code at some point? No errors were thrown so the error was not easy to locate. When debugging, I could see that the shininess value read from the file was in the thousands. I have no idea where...

Thank you Pavel, I'm not so used to collaborate with teams and git, so I've missed this feature. I will add other adds/changes and I will describe here what they do. Silverio

Shine world, Yes, NativeInt must be used not only in GLS.Scene but in all other units also. Instead changes in your fork you could include your improvements and fixies in https://github.com/glscene/GLXEngine/pulls I will add it later to the glxengine's trunk.

Hi everyone, I have been using GLXEngine for a while now and would like to share some, albeit small, changes I have made to better align the library's functionality with my needs. I'll leave it to the project managers to decide if there is any interest in including them in the original package. Not knowing how to proceed, I have fork the library in github and will include the changes as commits. Many features are not built into the library itself but as additional units. I always leave all decisions...

Lars, we have a GLS.Material range limited to TGLShininess = 0..128, so the code will have a compiler error if the value is out of range during the design time, but the fix if (TmpShininess >= 0) and (TmpShininess <= 128) then Shininess := TmpShininess else Shininess := 0; in GLS.File3DS may be justified for binaries. Done. Check out the glsl DiffuseShader demo, for example. Pavel

Range shininess fixed
-
Hi, I think I have located a bug. In unit GLS.File3DS, at line 1536, shininess is assigned directly as a result of the MaxInteger function. However, shininess is limited to 0..128 (TGLShininess = 0..128), and if the result of MaxInteger is outside that range the code simply fails without and error. To fix it, I have added code to first read to a temporary variable and then check the range before assigning. I don't have rights to do the change in the code base, so could someone fix ths? function GetOrAllocateMaterial(materials:...

Hi Pavel . It is always a pleasure to read from you. GLScene / GXScene that I am using are the best in the world even without any additional component. I am succeding to use it. Thank you very much

Hi, Sergio. Sorry that no one answered some of your difficult questions. Maybe you're working with a previous version of the scene and studio, and there are problems with that. I only have time to upgrade GLScene to the latest Rad Studio, and even then it's usually delayed. Everyone is busy with their own tasks rather than the engine. We need to create new components, such as TGLTerraGlobe and TGLPlanet, which can load and procedurally generate texture maps while moving objects. A spherical relief...

Dear friends, This is a goodbye. I want to express my gratitude to GLScene/ GLXScene forums , and the invaluable help I have received from Eric, Pavel Vassiliev, Pascal, and a few others (whose names I won't search in previous posts). I learned a lot from you. Sadly, over time, I've noticed that many others in the community are only focused on solving their own problems rather than offering help to others. At 71’s, I’ve learned that those who don’t help others rarely reach the top. In the last 2...

Hey Lars, Thanks for that - it's saved me days of effort. I got wrapped up in another issue that's needing sorted first. I was struggling to get sensible data from some TIFFs, but I think it's because they're way over the 4Gb limit and have been saved as BigTIFFs, so I need a Delphi unit/library that handles BigTIFF. Some months are just like the labours of Sisyphus .... Eric

Hi Eric, I struggled with this as well when I first implemented the TGLTerrainRenderer many years ago. It is not logic at all, but you need to normalize the vertical scale of TGLTerrainRenderer with the actual range of your data. The procedure below is taken out of context, but I think you can see what it is doing. procedure TGridTerrain.UpdateHDSScale; var HDSMaxAbsValue : Double; begin inherited; HDSMaxAbsValue := 32767; if (Grid.MaxValue - Grid.MinValue) <> 0 then begin if Abs(Grid.MaxValue) >...

Hi, So, at the moment, I have GeoTIFF files and I'm using TGLHeightField to display the grid and create a DEM. The GeoTIFF files are huge and the performance of TGLHeightfield has fallen offa cliff, so I'm looking at TGLTerrainRenderer instead. TGLHeightTileFileHDS seems to be perfect for what I need to do, so I'm trying to create the HTF file from the TIFF using TGLHeightTileFile. When trying to add the height value, my data consists of Single values, but TGLHeightTileFile.CompressTile(x, y, ts,...

Hello, How can I achieve the camera movement so that there is a point in the world (not in the screen center, camera does not have target), and the camera rotates and moves (based on mouse delta) in orbit around the target so that the point always remains on the exact same spot in the screen? I'm using the Cadencer to calculate cursor delta and rotate the camera, but I can't position the camera properly, where do I even get the projection matrix from when the render context does not exist yet?

I have both an integrated Intel GPU and a dedicated Nvidia and occasionally run into problems when the Intel card is the primary one - users report grey blocks overlaying part of the application and an inability to click certain areas. These go away when you switch to the Nvidia card, so I was wondering if this selection can be done programatically in the application, perhaps when you create the Rendering Context on initialization? TLDR: Can you select the graphics card to use from within the ap...

The order in the GLScene component object list sometimes plays a role, try moving the sprite to the top

My request was about the HUD Sprite of axis origins (tree arrows), which draw a gray border around the arrows objects instead to be full transparency.
-
If all .stl separated models correctly visualized then there is something wrong in your vm.json file. Try to change signs for " direction" in axes for .stl details. Or combine them in one model in some 3d editor.

Then I think you should use GeoTIFF format instead for such big sizes or try TImage32 from glscene/external/graphics32, and as option divide your image using splitter https://sourceforge.net/p/glscene/code/HEAD/tree/trunk/Examples/AdvDemos/Archipelago/Splitter/ like in Archipelago advdemo.

note that SailboatDemo is not a GLScene app. It uses Firemonkey 3D platform. On fmx 3d there is no dedicated UI interface for the 3d scene. 3D objects are part of form components ( 3d viewport childs). FMX 3d platform dev seems to be slow. A few projects use it, from what I see. One exception is GBE3D by Grégory Bersegeay, a set of components including dynamic grids like the wave surface. On the sail model on OPYC app, I used formulas similar to "thin airfoil theory" to calculate each sail segment...

Hi Pavel. Thank you very much. So easy to read the comtents with the debugger. I did not think on this. In the past I learned to create meshes in the code like the attached but never study properly how to go from 3D models in Blender or Freecad and convert them to meshes to import from GLScene (more or less like in IntensityMesh demo). Now I will go deep to do this . Soon I will post a demo and ask more questions.
-
Sergio, you can look at the data in the debugger and make sure there are no Japanese symbols. You can re-save this data there to a text CSV file. Again, this is like an isosurface (2D to 3D), and the real volumetric 3D data are voxels, which are usually processed to build isosurfaces using the marching cubes algorithm. Perhaps in your case it will be enough to use only a model of a thin-walled ship structure, but usually, for an accurate calculation of stresses and strength, a volumetric model with...
