v0.3

Changes

• Added ability to use textures, normal maps and specular maps in particles
• Implemented rotational mechanics (period & axial tilt)
• Added button to add a satellite to the selected particle with configurable mass, radius and orbital period
• UI improvements in scene generator
• Replaced "No vertical component" with a planar deviation slider for more control over positions of particles

v0.2

Changes

Not yet the final product but a substantial improvement over the last update, completely ditching rasterization and focusing on graphics. A summary of changes is listed below.

• Path tracing with PBR and Monte-carlo sample accumulation
• Elastic/inelastic collisions
• Scene configurator
• Bloom with HDR rendering
• Changeable background (milky way by default)
• Particle editor using ray picking
• Particle following
• Time controls and reversibility

Alpha v0.1
