PANGAEA ✅- Next Gen Dynamic Fast Terrain creation using GPU, Fluid simulation and Spline systems

[nasos_333]

PANGEA - GPU Fluid and Spline Based Terrain Generator

PANGEA is the new ARTnGAME major asset release, for Terrain generation based on a GPU enabled fluid simulator. The module presents a new way of sculpting of terrains using a real time fluid solution fully controllable by the user.

The system allows for real time manipulation and generation of effects like erosion and land sculpting, and is working directly on GPU for maximum performance.

A spline system is used to curve roads and rivers on the terrain, or place mountains and define terrain regions for editing.

Base version Features:

• GPU based terrain editing for real time performance on any of the effects, even the most demanding ones like erosion
• Fluid based erosion and real time curving of terrain with eroding water brush
• Global rain simulation to create rivers and river maps
• Direct application of solution to Unity terrains and creation of overlapping river map, with rivers flowing at run time
• Optional Mesh based terrain system with LODs
• Powerful stamp system with 3D preview, GPU accelerated, with brush scaling and rotation, replacing or additive stamping
• Direct real time Stamp of any 3D object with the Depth Map stamper
• Multi terrain editing, with brushes applied across 4 neighbor terrains
• Big Variety of Noise functions on GPU, for easy, fully parametric and fast terrain formation generation
• Various levels of Undo, state saving and restoration, non destructive spline based manipulation, roads and mountain definition
• Parametric GPU based Hex grid generation
• Physics based object placement system

Pro version features:

• Spline based control system for creating mountains, curving roads, rivers and creating stamp maps
• Mesh from spline and wall generation system
• Connection to ARCGis for real world map retrieval and use for the game map formation
• Procedural City and surrounding road and fields generator and auto terrain formation around it
• Meta mesh based object generation system for easily creating organic formations, rocks, caves etc
• Road generation system, with intersections, bridges etc
• Procedural buildings generation system
• Procedural rock generator
• OpenStreetMap data importer for building and roads

and many more features to be added until release.

Solution space (Rendertextures + Mesh terrain with LODs)

Solution passed to Unity terrain at various height settings

Transferring of the solution to Unity terrain at various heights, the system will have various ways of transferring the solution to final Unity terrains including adapting it to an existing terrain, or stamping it in a replacing way etc

An existing Unity terrain can also be set as initial height map and be further edited with the fluids system and the other asset tools and passed back to Unity terrain when finished.

Added more noise options, one of which allows splitting of land into fields using Hierarchical Voronoi tessellation.

A sample of the Hierarchical Voronoi tessellation in shader, this can also be used for generating a texture that will color the fields directly. A texture making module using the terrain tools is also in the works together with the terrain sculpting tools.

I am also adding a special preview mode to control the effect, by previewing the shader texture directly in the inspector when parameters are changed, like the above image, before the application to terrain.

It’s a lot going on in here I guess this is on the works? Happy New Year by the way : )

Happy new year

Yes, i have just finished the core and doing some urp and hdrp compatibility work and few other mostly usuability related features and will do the first release soon.

[Zimnel]

Just take your time, this seems like a heavy features one : )
