Hey, there!

I wanted to just pop in here and let you guys know about an open-source cross-platform 3D game engine that I've been contributing to called BDX.

What Is This?

Blender Game Export Mac Contact

Blender is a powerful 3D image and animation edition program which must be highlighted because, in addition to a powerful engine and a good interface, it is totally free. It offers a lot of options related with 3D modeling, animation, rendering, post-production, interactive creation and playback. Dec 27, 2016  Video editing in Blender means scrubbing through video. This is done quickly, the only really good way, by loading it into memory. This means that you should max out the machines ram. I would suggest that you by a machine and install linux in it a.

BDX is a 3D Java-based game engine integrated with Blender and powered by LibGDX. Being that it's integrated with Blender, it runs on Windows, Mac, and Linux. As it runs on LibGDX, it should export to Windows, Mac, Linux, HTML5, Android, and iOS.

Hahaha, OK, But Really, What Is This?

Overall, BDX is a fairly light 'engine' that's kind of a bridge between Blender and LibGDX. It provides advanced functionality that's not there under vanilla LibGDX (like per-pixel lighting, components, and input maps), and exports data from Blender to use in the engine. So it kind of turns Blender into a full game engine.

It's just easier to call BDX as a whole an 'engine' than explain it all completely, haha.

But Why, Though?

The biggest reason to use BDX is that it's Blender-integrated, which means that you don't need to import or export anything. You push P in Blender's 3D window, and the entire Blender scene gets exported to run. This means that in addition to there being no importing and exporting, Blender can directly serve as your world editor. You place things where you want, and they'll be there when you play the game.

The second is that in this integration is supported lots of built-in features that are available from Blender's GUI itself, like the materials, physics settings, object properties, parenting, and other things. For most of this stuff, we use the settings available under Blender's Game render mode (at the top of the 3D view), though BDX comes with a Blender add-on to add a couple of game-related panels (and perform the heavy stuff behind the scenes).

Another reason is that we have a clean, game-focused API, which makes things like moving, rotating, coloring, tinting, swapping materials or models for, or checking for collisions between GameObjects simple and pain-free. To make things easy, you can either code in Blender's text editor, or set up an IDE to code with (which I'd recommend). BDX can use either one.

And How???

We've got documentation over at the Github homepage. The General Overview page lists some of the features alongside some example code for you to see how the various aspects of BDX work. The creator of the engine has video tutorials up (which, by now, might be a bit outdated), and I've started on a set of written tutorials, though they're kinda... Well, they could be improved upon, haha. They just don't really go into making a full game, but rather explain the game development process from the beginning, more-so.

What's It Look Like?

Most of what you'd be looking at is just Blender, but here's some old shots, nonetheless.

Anyway, check it out!

Fire and Smoke

Fire simulation was added to the Smoke Simulator. The domain received major updates to improve performance and usability. Smoke can be emitted from mesh surfaces, without the need for a particle system. A smoke flow force field was added to improve interaction with other simulations. Colored smoke simulation and mixing is possible and the interaction of smoke with collision objects has been improved.

Mesh Modeling

The bevel tool now includes rounding and was otherwise much improved, preserving the requested bevel width more evenly and generating better topology. A new symmetrize tool was added to make mesh topology and data symmetric.

More Features

New features include: a tool transfer vertex weights from one mesh to another, antialiased viewport drawing, connected proportional editing in UV editor, improved DPX file read and write, more control over curve taper, collision masks in the game engine and improved camera title safe drawing.

Cycles Render

Support for writing custom shaders in the Open Shading Language is now available. Motion blur rendering was also added, to make moving objects and cameras appear blurry. There is also an anisotropic shading node, and BSDF nodes can now have different normals, which can be set using the new bump and normal map nodes.

Modifiers

The decimator was rewritten, and now preserves UV's and vertex colors, has an un-subdivide and a mode to dissolve vertices to create planar n-gons. A new laplacian smooth modifier can reduce noise or smooth the mesh while preserving edges and volume. A triangulate modifier was also added, which can be useful for creating game assets with baked normal maps.

Modeling

Improved bridge tool to bridge multiple loops at once, subdivision, surface blending and bridging face regions. New grid-fill tool filling a grid from edge loops, X mirror and projected proportional editing, snap to symmetry, face split option for dissolve, vertex connect cut across faces.

Cycles Rendering

Rendering performance has been improved on CPU and GPU and support for new GPUs was added. A new Mist render pass is available, Ray visibility is now supported for all light sources, and new Nodes have been added. Hair rendering on the GPU has been enabled as well.

Motion Tracker

Some new features and smaller improvements to existing ones were done for motion tracking. Main features are markers' position refining, which allows you to refine marker position after it was occluded by an object, and automatic keyframe selection, which tries to automatically find a best keyframe for the reconstruction.

Physics

Smoke has improved rendering quality avoid blockiness, and subframe simulation support to handle fast moving emitters. Particles can now be emitted from faces generated by modifiers that were not in the original mesh.

What's New:

The Blender Foundation and online developer community is proud to present Blender 2.71. Much awaited new features for Cycles renderer include deformation motion blur, fire/smoke and volume rendering and a baking API. User interface now allows for draggable popups and resizable preview widgets. Animation has new interpolation types with “easing equations” presets. Modeling now allows to “split normals” and Sculpting/Painting has new HSL color wheel and constant detail in dyntopo. Game development now allows deactivating logic bricks, multi-threaded animations, cast only materials and “unlimited” action layers. Freestyle NPR rendering has a new textured strokes feature, along with line sorting options.

Cycles Rendering

Cycles now includes support for rendering volume textures, fire and smoke, deformation motion blur, baking textures from cycles materials, more texture interpolation modes and a dedicated UV layer node.

Animation

More easing equations added to the IPO editor for better animation control, locking time to other windows is again possible, auto snapping is now independent from display type.

The user interface now offers more feedback, especially on errors, updates driver expressions automatically on editing, includes more icons and offers more editing tools.

New tools also include lasso selection support, non-linked duplication for strips, and setting preview range based on selected strips.

Modelling

The new per-face normals feature allows blender to display and export sharp edges correctly without geometry duplication.

In addition, selection tools offer more options.

Sculpting/Painting

New features include a HSL color wheel for color selection and tools to handle homogenous density in dynamic topology sculpting.

Dyntopo and matcap display for sculpt mode have also had performance optimizations.

Game Engine

UI to deactivate logic bricks, multi-threaded animations, shadows-only materials and more action layers are among the new features for the game engine

Freestyle NPR Rendering

Freestyle has been upgraded with textured stroke support. Textured stroke support makes it possible to apply patterns to the lines and simulate rough surfaces or different kinds of brush tips for the strokes themselves.

Line sorting also gives artists more control over the order of line drawing
