3D-Tech News Around The Web / Synthclipse 0.9.17 GLSL shader prototyping tool
« Last post by JeGX on May 11, 2015, 08:28:39 PM »
Quote
Synthclipse is a GLSL shader prototyping tool. It makes possible to fast develop all kinds of shaders: Fragment (FS), Vertex (VS), Geometry (GS), Tessellation (TS) and Compute (CS). Shader development can be done using, compatible with Fragmentarium and Shadertoy (but limited to FS and VS), Fragx shaders or by using fully featured JavaScript JSX scripts. The JSX API is consistent with WebGL but in fact exposes complete OpenGL 4+ API.

Synthclipse is based on Eclipse IDE and depends on Eclipse CDT (C/C++ Development Tooling). It pretends that GLSL is just plain C++ code.

3D-Tech News Around The Web / Khronos Releases SYCL 1.2 Final Specification

SYCL (pronounced ‘sickle’) is a royalty-free, cross-platform abstraction layer that builds on the underlying concepts, portability and efficiency of OpenCL that enables code for heterogeneous processors to be written in a “single-source” style using completely standard C++.   SYCL enables single source development where C++ template functions can contain both host and device code to construct complex algorithms that use OpenCL acceleration, and then re-use them throughout their source code on different types of data.

3D-Tech News Around The Web / ClanLib 4.0 released
« Last post by JeGX on May 11, 2015, 08:19:42 PM »
ClanLib is a cross platform C++ toolkit library with a primary focus on game creation. The library is Open Source and free for commercial use.

Quote
The ClanLib C++ Game SDK has been updated. Key updates since previous release include a path drawing module using CPU/GLSL to render anti-aliased SVG style primitives (including lines). Now fully supports Windows, Mac OS X and Linux. All source has a very liberal zlib style license

3D-Tech News Around The Web / (WebGL) A trip under the moonlight

A trip under the moonlight is an experimental demo.
The aim was to explore ways to achieve a realistic landscape with current web technologies.
It uses an implementation of the Fast Fourier Transform on GPU to simulate waves displacements. The ocean rendering is done is screen space coordinates, allowing a great quality.
You can travel by using the keyboard and select the environment.

Requires some extensions that Nexus 4 (Adreno 320) is missing :P

Spring - WebGL(html5)
                It's so lovely when it arrives...
                But you always forget about those damn fly's and shit!
                Tried to do some fake lightning with lightshafts and stuff to set the mood.
                Probably quite heavy and not very mobile-friendly.
                Done using "https://github.com/mrdoob/three.js"

3D-Tech News Around The Web / Bullet Physics SDK 2.83 released
« Last post by Stefan on May 08, 2015, 06:18:12 PM »
Bullet 2.83 released on github

You can download the Bullet 2.83 release from github here

See the docs/BulletQuickstart.pdf guide as part of the SDK download.

Some of the features include:
  • A new example browser, based on OpenGL 3+. It is still work-in-progress and not all demos have been ported over yet. Still, it is a better way to explore the Bullet SDK.
  • Import of URDF files, universal robot description files. A URDF file can be imported as rigid bodies (btRigidBody) or as multi body (btMultiBody). See the example browser under importers.
  • Improved support for btMultiBody with multi-degree of freedom mobilizers, thanks to Jakub Stepien. See examples/MultiBody/MultiDofDemo.
  • New btGeneric6DofSpring2Constraint, replacing the old one. Thanks to Gabor PUHR and Tamas Umenhoffer. See the example browser under API or examples/Dof6Spring2Setup.
  • OpenCL demo integrated in the ExampleBrowser. The demo is disabled by default. See docs/BulletQuickstart.pdf how to enable it.
  • Implicit integration of gyroscopic forces. See example browser under API/Gyroscopic for the Dzhanibekov effect.
Please enjoy, and expect improvements in future releases.
