In my previous posts, I used perspective projection cameras to cast projections onto the ground. This time, I replaced the perspective projection with an orthographic one, placed it at the Sun’s position... and let time begin to move. Pure delight.

If you combine projections from each side of a cube, you can approximate shadows from a point light source.
The video shows the idea very clearly: several simple projectors working together around the object.

Accidentally discovered a fun trick while playing with projective shaders in OpenGlobus:
camera depth projections can work like square-shaped lights.
And they cast shadows!

🇺🇸🇺🇸 This will be awesome!! 🇺🇸🇺🇸
We're building a Moon Base!
@NASAMoonBase will serve as a habitat where astronauts live and work during long-term science missions.
Join us at 2pm ET on Tuesday, May 26, for a live news event where we’ll share updates on our lunar exploration plans: go.nasa.gov/4uinkLi

I just tried Mapterhorn terrain in OpenGlobus - and my first impression is literally: WOW, it looks amazing!
Clean, detailed, visually pleasant relief, and it loads surprisingly fast. Really like the idea behind it: open-data terrain built for modern web mapping. Huge respect to @leichteralsluft for pushing this forward.

Small but important rendering update in OpenGlobus v1.
I migrated the text rendering pipeline to MTSDF, which improves font sharpness, outline quality, and fixes several rendering issues with special characters.
Live examples:

Atlas generation is based on Chlumsky’s excellent msdf-atlas-gen:

Next step: Arabic text and complex font support.

OpenGlobus v1.0 lighting system progress demo: the object is now consistent with the scene’s lighting, sun, and atmosphere. As the model moves, you can see the changing highlights, reflections, and fuselage illumination, especially under the low sunset sun.

OpenGlobus 1.0 runs smoothly even on this old smartphone. Over the last few months, I rebuilt and improved nearly 80% of the engine, enabling support for advanced rendering techniques such as HDR, PBR, Cascaded Shadow Maps, deferred forward rendering, Order-Independent Transparency, multi-frustum rendering, reverse depth, and full orthographic camera support. In other words: it feels like the whole planet is in my pocket. 🌍📱😄

You are looking at one of the most detailed 3D reconstructions of a humancell (eukaryotic cell) ever made.
Every molecule. Every structure. Mapped in extreme precision.
This isn't just a pretty picture. It's a microscopic universe finally brought into focus.

Hey everyone 👋
I’ve been working on the next version of OpenGlobus and honestly - it’s shaping up to be something much bigger than just an update.
I’m rebuilding everything from the ground up: the engine itself, the plugins all of it. The goal is to make it faster, cleaner, and more looks like real engine.
So far:
- Performance is about 3x better
- The engine has a bunch of new capabilities
- Plugins are getting a serious upgrade too.
