Hello all !

My name is Soumitra Saxena. I'm in my prefinal year , studying Electronics
Engineering at the Birla Institute of Technology and Sciences , Pilani ,
India. I've taken a keen interest in Computer Graphics/OpenGL for the last
2 semesters and am very excited to apply for GSOC under Crystal Space.

Basic Terrain Generation has been a project of mine , both at a personal (
https://medium.com/code-adventures/cccf50e961a9) and academic level. I've
also tried my hands on a basic planet generation using terrain maps (
https://medium.com/code-adventures/9df442973626).

 I've also done a bit of scripting and GUI implementation in Maya (toolkit
for Cloud Generation)

A GUI Editor for Terrain seems to be a fantastic addition to the Crystal
Space interface. I thought of a rough prototype for a GUI Editor. Here is
the rough map -

A GUI Editor for Terrain -


A 3D GUI Editor for Terrain , based on the flexibilities provided by the
cseditor framework. Modelled on Maya's Editor for Fluids and Terrain (kind
of) . Single iSpace with panels containing  the Tools. Add flexibilities
like toggle wireframe/textured , rotation , zoom , viewcube etc. Can even
add quick view options like Isometric and Orthographic angles. The
following tools can be provided for improved functionality , leveraging
Crystal Space's terrain handling libraries. We are basically making an
interface so that a new user feels comfortable with terrain generation and
does not have to worry about the pipeline behind it :

Tools to be implemented in the panels :

1. Generate Mesh tool :

a.Set number of cells and size of mesh.

b.Generate Flat Terrain with standard material and proceed to Edit it using
the Terrain Edit Tools.

c. Set Properties like Max Height  , Mean height , Median height.

d. Preloaded presets - Desert , Grassland , Ice

2. Generate Terrain tool:

a. Load Heightmap and generate terrain , save values in the mesh to edit
later.

b. Set values like Max Height , weight and Resolution.

3. Material Properties :

a. Set attributes like Material Color , Material Type ( Phong , Blinn etc)

4..Edit Mesh tool :

a. Selectable points in the mesh using Mouse pointer . On click , 3D
Transformation tool appears , user can use deformations. Add option of
toggling off texture (display wireframe).

5. Paint Terrain tool :

a. Splatting Textures - Select a splatting texture from a list of textures.
Mouse cursor changes into the type of texture. Paint over the standard
texture with the chosen texture.

b. Choose from a variety of colors , terrain presets ( dust , grass , ice).

6. Add Object Tool (maybe):
a. From a list of objects to add , choose the desired object to add on the
terrain (e.g. Models of rocks , flora , fauna). (Drag and Drop interface.)
 I'm currently going through a couple of libraries ( libNoise) which could
also be used for Coherent Noise generation , which can be used in the
Generate Terrain tools to generate realistc terrains.


*Please tell me what you all think about it ! All the Feedback is valuable
!*
Thanks a lot for reading !

Regards ,

Soumitra Saxena
