I want those triangles on the edge to be the same colour as the rest of the flat ground, not the side of the cliff
my normal calculation is done here, with 2 ways to calculate (left or right handed, i can never remember which way the strip is oriented) but neither of them seem to solve the problem:
void ClipMap::setNormals(unsigned int ii, unsigned int jj, Distant& theDistant){ normals_1[ii][jj].members[0] = 0; normals_1[ii][jj].members[1] = 0; normals_1[ii][jj].members[2] = 0; normals_2[ii][jj].members[0] = 0; normals_2[ii][jj].members[1] = 0; normals_2[ii][jj].members[2] = 0;/* method 1 if ( (ii < theDistant.size2n) && (jj < theDistant.size2n) ) { normals_1[ii][jj].members[0] = (float)sectors[ii+1][jj].height - sectors[ii][jj].height; normals_1[ii][jj].members[1] = -1; normals_1[ii][jj].members[2] = (float)sectors[ii+1][jj+1].height - sectors[ii+1][jj].height; } if ( ii != 0 && jj != 0 ) { normals_2[ii][jj].members[0] = -(float)sectors[ii-1][jj].height + sectors[ii][jj].height; normals_2[ii][jj].members[1] = -1; normals_2[ii][jj].members[2] = -(float)sectors[ii-1][jj-1].height + sectors[ii-1][jj].height; }*/ if ( ii < theDistant.size2n && jj > 0) { normals_1[ii][jj].members[0] = (float)sectors[ii+1][jj].height - sectors[ii][jj].height; normals_1[ii][jj].members[1] = -1; normals_1[ii][jj].members[2] = (float)sectors[ii+1][jj].height - sectors[ii+1][jj-1].height; } if ( ii > 0 && jj < theDistant.size2n ) { normals_2[ii][jj].members[0] = -(float)sectors[ii-1][jj].height + sectors[ii][jj].height; normals_2[ii][jj].members[1] = -1; normals_2[ii][jj].members[2] = -(float)sectors[ii-1][jj].height + sectors[ii-1][jj+1].height; }}and this is the drawing function that increments on j:
for (unsigned int i = 0; i < theDistant.size2n; i++) { glBegin( GL_TRIANGLE_STRIP ); for (unsigned int j = 0; j <= theDistant.size2n; j++) { int iunit = i*unit_secsize; int junit = j*unit_secsize;... glNormal3fv(normals_2[i+1][j].members); glVertex3i(iunit+unit_secsize, sectors[i+1][j].height, junit); glNormal3fv(normals_1[j].members); glVertex3i(iunit, sectors[j].height, junit);...}}the normals and heightmap exist in the clipmap class
class ClipMap{ public: int level; int tvect_x; int tvect_z; float tvect_x_secsize; float tvect_z_secsize; int unit; int unit_secsize; int half_unit_secsize; int side; int width; float zBuf_inner; float zBuf_outer; int player_mod_x; int player_mod_z; unsigned int clip_l; unsigned int clip_u; unsigned int shiftmod_x; unsigned int shiftmod_z; unsigned int shiftmod_not_x; unsigned int shiftmod_not_z; unsigned int shiftmod_notx_notz; unsigned int shiftmod_x_and_z; unsigned int shiftmod_notx_and_z; unsigned int shiftmod_x_and_notz; Sector sectors[257][257]; Vectorf normals_1[257][257]; Vectorf normals_2[257][257]; inline void setPlayerMods(Player& thePlayer); inline void setTvects(Distant& theDistant, World& theWorld); inline void setClips(Distant& theDistant); inline void setShifts(Distant& theDistant); void setMeta(int F, Distant& theDistant, World& theWorld); void setVars(Player& thePlayer, Distant& theDistant, World& theWorld); void setSectors(Player& thePlayer, Distant& theDistant, World& theWorld); void setNormals(unsigned int ii, unsigned int jj, Distant& theDistant); void setAllNormals(Distant& theDistant); void shiftSectors(int x, int z, Player& thePlayer, Distant& theDistant, World& theWorld); void drawSea(Distant& theDistant, float sealevel); void drawMap(Game& theGame, Distant& theDistant);};(In the preview the '+' sign is not showing up in the array notation so it looks like 'i 1' but it should be 'i+1')
