Black Shark Graphics Engine

[BlackShark]

Hello!

I am hurry to share my first official release!
 
Black Shark Graphics Engine is a simple 2D and 3D engine written in Pascal for developers to produce applications utilising hardware-accelerated graphics. It supports Lazarus (versions >= 2.0) and Delphi (Community Edition 10.3, another versions haven't been tested).

New minor version 1.01:
- found and removed a bug in build of a path;
- edited test of KD-tree - it was reduced 2d level displayed objects, otherwise they intersect scrollbars;
- gallery was updated.

Best regards,
BlackShark

BlackShark  nice job
i test this library 

It works but it is a small problem
Example :
When you test a fish or globe scene and go to another scene and go back the graphic disappears

[nouzi]

I think it's a leak in  memory

Thank you!

I have found out: some tests with a canvas rotate a frustum for its testing, but when you return back to 3d-test, the frustum remains rotated. If you will insert

Code: Pascal  [Select][+][-]

1. Scene.Frustum.Angle := vec3(0.0, 0.0, 0.0);

when the test is creating you get the same image what you saw in begining.
I will think about the problem.

There are not leaks: memory is swimming slightly, but on 4-5 iteration of select of the tests remains on the same level. Furthermore, in Delphi I always use ReportMemoryLeaksOnShutdown := true and there memory leaks are not shown. Any way, thank you very much for testing.

I improved a little more:
- was improved mechanism releasing of textures - texture-singleton is released if it is not used already;
- 3d tests were changed - it added reset of the frustum orientation;

Hello!

I am glad to announce new version 1.02 of my engine (bshark.org):

• a viewer of schemes has been released;
• some gui-components have been improved;
• a mechanism of storage and recovery states of GUI (with RTTI) has been accomplished;
• a test of the viewer of schemes has been added (bs.test.scheme.pas);
• the gallery has been updated.

The version while hasn't tested on Linux.

Nice! Always great to see more libraries in this category for Pascal, especially ones as fully featured as yours.

Thank you for kind words! I hope it will be useful for someone.

Thank you for kind words! I hope it will be useful for someone.

Most likely for 3D losers, like me. Thank you very much .

I am glad to announce new version 2.0 of my engine bshark.org:

• license agreement was changed from custom on free LGPL;
• a support of hardware multisampling was added;
• FMX viewport support was added, I ran it only, while is not tested widely yet;
  
• the canvas (TBCanvas) and its objects:
  • a new common mechanism of scale;
  • options of align: anchors, margins, paddings, and patterns of align (TObjectAlign) were implemented;
  • TFreeShape - a free shape builder with closed counters (see gallery);
  • TFog - a simple rectangle background with a custom shader;
  • TCanvasLayout - invisible and is not utilizing GPU resources rectangle object;
  • TPath - added drag-drop for reference points;
  • TrapezeRound;
  • TMultiColoredShape;
  • TColorSelector;
  • TBiColoredSolidLines;
  • TBlackSharkPen was removed;
• new controls:
  • TBEdit;
  • TBSpinEdit;
  • TObjectInspector;
  • TBForm;
  • TBColorDialog;
  • TBColorBox;
  • TBTrackBar;
  • TBGroupBox;
  • TBCheckBox;
  • TBTable;
  • TBComboBox;
• quality fonts rasterisation was a few improved;
• RTTI format translated from binary to xml for possibility compare differencies by VCS;
• KD-Tree was implemented with TBlackSharkKDTree;
• refactoring of the TBScene:
  • rendering was taken out to bs.renderer;
  • translated to KD-tree;
• refactoring controls: TBScrolledWindow, TBScrollBar, TBButton;
• added a new class THashTable to bs.collection;
• context initialization:
  • translated to a shared context;
  • smart initialization - without eglChooseConfig by selection of attributes from desirable to supported;
• management of fonts, textures and shaders was translated to global mode, now they are have common manadgers for all contexts;
• new project for autotests (AutoTests.dpr);
• new methods in TBlackSharkViewPort for support of autotests (beginning from "Test");
• updated libEGL and libGLESv2 libraries for Windows;
• an option hardware multisampling was placed to BSConfig.Multisampling;
• now by default only one thread is run for animations and events (the same global GuiThread) (see bs.thread.CreateThreads); you can change it in any time;
• lot of bugs were fixed in space bs.scheme.

Great Works!
Can you increase the anti-aliasing function of the image?
like C# GDI+:
 graphics.SmoothingMode = SmoothingMode.AntiAlias;

Great Works!

Thanks!

 graphics.SmoothingMode = SmoothingMode.AntiAlias;

I have concentrated the settings in the class bs.config.BSConfig and will continue to expand them there. Now unfortunately there is only one options of smoothing. I will try to improve smoothing modes, for example add the number of samples for supersampling. I also want to add to the settings other methods of full screen antialiasing that I previously implemented on shaders.
