Hello i have question, how create 3D grass in panda3d for HeightfieldTesselator or GeoMipTerrain ?
is there an example code?
how to be efficient (you have to add and remove grass dynamically, with a lod)
for example i search to add 3D to roadming ralph sample, grass
the grass must be visible near ralph and disappear if it is far away
Maybe it’s possible, i view this video example :
but i don’t found source code with 3d grass and tree, i installed thi program and run sampler but i have only terrain without grass or tree.
i run roaming ralph too and i have not water :
why ? it’s bug ?
Where is the full version of the program instead of this poor version? Is there anything else to download?
drophbox source code not exist i have 404 error
I’m looking solution with heigmap technicle
I want add 3d grass with “grassmap”, when it’s black i add 3d grass and when is white i add none.
I can do it in panda3d with 2d textures in glsl, but i don’t for 3d object
like this :
hmap = loader.loadTexture(“Data/Terrain/” + layout + “/heightmap.png”)
hmap.set_wrap_u(Texture.WM_clamp)
hmap.set_wrap_v(Texture.WM_clamp)
hmap.set_format(Texture.F_r16)
node.set_shader_input(“heightmap”, hmap)
nodeShadow.set_shader_input(“heightmap”, hmap)
fmap = loader.loadTexture("Data/Terrain/" + layout + "/flowmap.png")
fmap.set_wrap_u(Texture.WMClamp)
fmap.set_wrap_v(Texture.WMClamp)
node.set_shader_input("flowmap", fmap)
for material in ['rock', 'grass', 'gravel', 'snow', 'moss']:
for i in xrange(2):
tex = loader.loadTexture("Data/Terrain/Materials/" + material + "_" + str(i+1) + ".png")
tex.set_wrap_u(Texture.WM_repeat)
tex.set_wrap_v(Texture.WM_repeat)
tex.set_format(Texture.F_srgb_alpha)
tex.set_minfilter(Texture.FT_linear_mipmap_linear)
tex.set_magfilter(Texture.FT_linear)
tex.set_anisotropic_degree(16)
node.set_shader_input(material + ("Diffuse" if i == 0 else "Normal"), tex)
i want same technical with hmap but i want to add 3d grass and 3d tree for example, it’s possible ?
