I have successfully drawn a golf course, but does anyone know how to draw the slopes smooth? The current drawing is lumpy and looks like Minecraft. I use DEM data for drawing terrain. [スクリーンショット 2024-04-21 17.11.14]

The slopes look pretty smooth - the more problematic part seems to be a low resolution of your texture :face_with_monocle:?

Thank you. If the resolution of the texture image were better, would it improve the stair-like forest slope?

I have found that the DEM data is not good because I could not solve the problem by increasing the resolution of the image. Thank you for your reply.

[image] Seiji_Chishiki: I use DEM data for drawing terrain I have never worked with DEM data, but it looks like it it depends on how you convert elevation data into a mesh. The following illustration shows raw DEM data (left), Minecratfish mesh (middle), smoother mesh (right). Maybe your curr…

I’ll try to fix the DEM data because I’ve found some error data in the DEM data… Thank you.

[image] Terrain height map banding Questions It’s the limitation of using an image. The numbers of steps available is very limited (128 -256 max) To go beyond this limit you have to process the data with a smoothing function to average positions, and get billions more. H…

The following class is from Simon Dev’s tutorial on terrain generation. class Heightmap { constructor(params, img) { this._params = params; this._data = graphics.GetImageData(img); } Get(x, y) { const _GetPixelAsFloat = (x, y) => { const position = (x + this._data.width * y…

Thank you. The DEM data I have is elevation CSV data downloaded from the Geospatial Information Authority of Japan.
