I have released version 0.34-3 of sfsim.Reentry shockwave visuals are now integrated into the game! The shockwave’s shape changes with the vehicle’s speed, while its brightness depends on the rate at which energy is converted into heat. Getting the shockwave t…

I am excited to share early results of shockwave rendering with the community!I would like to add visualization of a glowing shockwave during atmospheric reentry in the sfsim spaceflight simulator. I explored possible approaches by discussing the problem with …

I have released version 0.30-1 of sfsim.This release introduces a major overhaul of the rendering code as well as a runway for the spacecraft. The rendering system is implemented using the Clojure programming language as well as GLSL. LWJGL3 is used to access …

Currently I am working on deferred shading. This requires me to separate rendering into two passes:Geometry pass: render data to a point buffer, normal buffer, and a color buffer, etc.Lighting pass: use the geometry buffers to compute lighting including shadow…

Hi,Here is release version 0.23-1 of sfsim.I started adding achievements to sfsim.To begin with I added the following achievements:breaking the sound barrier: spacecraft exceeds speed of soundcrossing the Kármán line: spacecraft reaches altitude of more than 1…

Hi,Here is release version 0.22-1 of sfsim.I added rate pointers for roll, pitch, and yaw angles to the MFD. The pointers are arranged around the navball in the center.Top: roll rate indicatorRight: pitch rate indicatorBottom: yaw rate indicatorSee here for a …

Hi,I have released version 0.21-1 of sfsim.The new version of sfsim shows a navball in the bottom right corner of the window. At the moment I configured it to show pitch and roll angle relative to the Earth’s horizon and yaw angle relative to the orbital plane…

Hi,I have released version 0.20-1 of sfsim.sfsim now has an orbit display to make launching into an orbit easier. The orbit display shows a visualisation of the planet Earth and the orbit as well as several orbital parameters:periapsis altitudeapoapsis altitud…

Hi,I have released version 0.19-1 of sfsim.This version introduces scaling of the graphical user interface. All the user interface elements are scaled up when switching to fullscreen or back taking into account the monitor resolution. This should make it easie…

Hello spacers,I released version 0.15-1 of sfsim. sfsim is a realistic 3D space flight simulator with an advanced single-stage-to-orbit space craft.This version displays some orbital information:height of periapsis above surfaceheight of apoapsis above surface…

Hello everyone,I released version 0.11-2 of sfsim. sfsim is a realistic 3D space flight simulator with an advanced single-stage-to-orbit space craft.I have now added several sound effects and a music track:Added Andrewkn’s At the Edge of Space for the event wh…

Hello everyone,I released version 0.6-1 of sfsim. sfsim is a realistic 3D space flight simulator with an advanced single-stage-to-orbit space craft.The graphics implementation is now using deferred rendering to improve performance and facilitate rendering of s…

Hi, I finally managed to release version 0.5-1 of sfsim. sfsim is a realistic 3D space flight simulator with an advanced single-stage-to-orbit space craft. The new version comes with rocket plume graphics. The plume was implemented using OpenGL shaders and use…

Hi, Version 0.4-1 of sfsim comes with a following camera and improvements to the physics engine. The camera now follows the vehicle and the orientation is controlled using the speed over ground vector. The numerical keypad can still be used to control the came…

Hi,I finally got the first version of the joystick configuration dialog working. One can configure axes and buttons in the dialog. There also is a common dead-zone setting for all joystick axes. The configuration can be saved using the save button. The config …

Hi everybody! I have just pushed a playtest build to Steam and the button to join the playtest is visible on the sfsim page now. Before you join, please be aware that sfsim is still very much a work in progress and a lot of things are still missing! Also check…

I have created landing gear animations with Blender, baked them, and exported the result to glTF. "Inverse kinematics", "Damped track", and "Child of" constraints where used to ensure that torque link, resistance rod, and piston are animated correctly. Animati…
