0000259: Optimize Transparency Rendering for less-translucent objects

Thu, 01 Aug 2024 15:34:10 +0200

In v1.1.1.3048 we've implemented embedded FragmentDepth Rendering for better transparency weighting of less-translucent objects.
Translucent objects with high opacity value were weighted equally like all other translucent objects.
We now pre-render fragment depth of the scene with the most front vertex depth.
This value is then used to detect how far a fragment is away from that vertex. The closer it is, the higher the weighting
and the better less-translucency becomes.

0000258: Multisampling Support in Rendering Pipeline

Thu, 01 Aug 2024 15:31:02 +0200

Multisampling Support in Rendering Pipeline (MSAA) implemented.
Also working in combination with FXAA.

0000237: Bug: Volumetric Mesh Rendering defect

Thu, 01 Aug 2024 15:29:15 +0200

Volumetric Mesh Rendering is not correct anymore. Parts of the mesh getting clipped.

0000241: Bug: design time marking of selected elements not visible

Thu, 01 Aug 2024 15:28:48 +0200

User interface seems to be disturbing, because selected 3D elements are not marked as selected, or the bounding box is overwriting it.
We need to find a better way to display selection and element size in the ide at design time.

0000257: JOLT Physics Support

Thu, 01 Aug 2024 15:28:20 +0200

JOLT Physics Support for x64/x86 at first

0000238: Feature: Cone + Cylinder colliders for Q3 Physics

Thu, 01 Aug 2024 15:27:40 +0200

Implement cone and cylinder colliders for Q3 physics.

0000256: Bug: TGorillaMesh.GetBoundingBox() computation not correct

Mon, 08 Apr 2024 18:15:20 +0200

TGorillaModel and TGorillaMesh.GetBoundingBox() computation is not correct.

0000255: Bug: TGorillaMesh.BoundingBox computation not working correctly for all hierarchies

Mon, 08 Apr 2024 18:14:59 +0200

Here we've detected a misconception within FMX. BoundingBox computation in FMX only happens for TMeshData on vertex data, but not for hierarchies in a mesh collection.
This is different to expected behaviour in Gorilla3D.

0000254: Bug: FMOD crashes with "invalid handle" or "channel reused by other sound" message

Wed, 14 Feb 2024 08:24:15 +0100

Due to the priority system of FMOD channel handles might get invalid or getting stolen by other sounds.
This becomes an issue on working with the designtime collection items (TGorillaFMODSoundItem).
Here we keep the channel interface as field value.
When it becomes deprecated, accessing this handle causes the exception.

To solve this, we need to implement a channel callback and react on the FMOD_CHANNELCONTROL_CALLBACK_END callback.

0000251: Feature: PickTriangle function for TGorillaMesh/TGorillaModel/TMeshDef

Thu, 08 Feb 2024 18:04:33 +0100

We need to implement an easy to use method to pick a triangle of a mesh (out of a hierarchy).
The method should return the 3 coordinates of the triangle.

0000252: Bug: RayCastIntersect not always working

Thu, 08 Feb 2024 18:04:21 +0100

In case of having a model with a hierarchy of sub meshes, the default RayCastIntersect is not working properly.
The reason for that lies in FMX TControl3D.ObjectAtPoint() routine.
Here always the top-level InverseAbsoluteMatrix is applied to all meshes a raycast is performed.
Therefore the wrong or no mesh is intersected.

0000253: Bug: FMODSoundItem (not looped) can only be played back once.

Thu, 08 Feb 2024 18:04:05 +0100

In case of working on a TGorillaFMODSoundItem, which is not looped, it can only be played back once.

0000239: Bug: Q3 Physics crashes, with ckMesh collider

Thu, 01 Feb 2024 12:24:27 +0100

ckMesh is crashing with GetBVHNodes out of list range when assiged to a capsule
ckTerrain also crashing with GetBVHNodes if another collider is inside of the bounding at physics start.

0000250: Bug: DesignCamera in Reflection Render Pass forbids to set user-specific camera in viewport

Thu, 01 Feb 2024 12:22:54 +0100

When the design camera is linked in the reflection render pass controller, it is not possible to set a user-specific camera in the viewport.
The wrong camera was restored in reflection render pass.

0000249: BUG: PBR Material not correct multiple light source computation

Thu, 01 Feb 2024 12:02:14 +0100

When having a point light source and a spotlight source pointing towards the same object, the second light source only gets computed.
For lambert, phong or blinn-phong it is working.

0000248: Bug: OBJ loading failed on irregular grouping

Fri, 05 Jan 2024 08:56:36 +0100

Some OBJ structures failed to load due to irregular mesh grouping.
We need to solve this by a CurrentGroup mechanism

0000247: Bug: glTF model failed to load on "COLOR_0" wrong format

Fri, 05 Jan 2024 08:55:03 +0100

A version of Blender exported models with unnormalized vertex colors.
Instead of the recommended float type, a USHORT or UByte was exported.
We need to implement those datatypes to solve the issue.

0000246: Bug: Wind Material Behaviour incorrect direction on rotated model

Fri, 05 Jan 2024 08:52:54 +0100

The wind material behaviour uses a shader with incorrect wind direction, if the applied model is rotated.
The wind direction also needs to be transformed by the model's modelmatrix.

0000245: Stiff joints are flexible

Mon, 11 Dec 2023 08:34:30 +0100

Two spheres attached by a stiff joint fall down on a cube
and start looping around with increased distance between them
like attached by an elastic

0000244: Bug: Uninstallation or putting a Viewort3D onto a form crashes with installed Gorilla3D package

Fri, 10 Nov 2023 13:48:35 +0100

Due to unexpected OpenGL errors if a HWND is not available yet, leads to a crashing IDE.

0000243: Bug: Sketchfab Plugin not downloading in v12.0 (400 Bad Request)

Thu, 09 Nov 2023 16:24:05 +0100

In Delphi 12.0 Athens we're receiving a "400 Bad Request" response on downloading assests from AWS by Sketchfab Plugin. It's working fine until 11.3.

0000242: Feature: Gizmo to control elements and to navigate in the scene at design time

Mon, 06 Nov 2023 15:09:04 +0100

Users requested a gizmo to control elements and to navigate in the scene at design time

0000240: Feature: Solve car/wheel joints for simulation

Mon, 06 Nov 2023 15:06:16 +0100

Implement a car/wheel joint or a combination of existing once to solve wheel simulation

0000231: C++ Builder include-directories are not set by the installer

Mon, 06 Nov 2023 15:02:50 +0100

For the users of C++ Builder, the include directories set by the installer are not sufficient to get the compiles running.
In order for the compile to pass, the folloring would be needed, too:

In project->options->Building->C++ Shared options, add

\Win32\Release\C\hpp to Include path under All configurations - Windows 32-bit platform

\Win32\Release\C to Library path under All configurations - Windows 32-bit platform

\Win64\Release\C\hpp to Include path under All configurations - Windows 64-bit platform

\Win64\Release\C to Library path under All configurations - Windows 64-bit platform

Perhaps they could be set by the installer or maybe they could be mentioned in the installation guide?

0000233: Gorilla.Assetsmanager throws "unknown type name 'GUID' on C++ Builder

Fri, 27 Oct 2023 11:37:37 +0200

Probably only related to C++ Builder:
If Gorilla.AssetsManager.hpp is added to the #include:s either by directly or indirectly by, for instance, including Gorilla.Model, the compile fails with the errors
[bcc64 Error] Gorilla.AssetsManager.hpp(655): unknown type name 'GUID'
[bcc64 Error] Gorilla.AssetsManager.hpp(656): unknown type name 'GUID'
