From 0df5c01a8ce927c33ae9b67f459365505b980c33 Mon Sep 17 00:00:00 2001 From: kwolekr Date: Fri, 20 May 2016 03:37:31 -0400 Subject: Mapgen: Remove calculateNoise from most mapgens This commit moves noise calculation to the functions where the noise is actually required, increasing the separation of concerns and level of interdependency for each mapgen method. Valleys Mapgen is left unmodified. --- src/mapgen_fractal.cpp | 22 ++-------------------- 1 file changed, 2 insertions(+), 20 deletions(-) (limited to 'src/mapgen_fractal.cpp') diff --git a/src/mapgen_fractal.cpp b/src/mapgen_fractal.cpp index dca10d253..f54de6275 100644 --- a/src/mapgen_fractal.cpp +++ b/src/mapgen_fractal.cpp @@ -243,9 +243,6 @@ void MapgenFractal::makeChunk(BlockMakeData *data) blockseed = getBlockSeed2(full_node_min, seed); - // Make some noise - calculateNoise(); - // Generate base terrain, mountains, and ridges with initial heightmaps s16 stone_surface_max_y = generateTerrain(); @@ -328,23 +325,6 @@ void MapgenFractal::makeChunk(BlockMakeData *data) } -void MapgenFractal::calculateNoise() -{ - //TimeTaker t("calculateNoise", NULL, PRECISION_MICRO); - s16 x = node_min.X; - s16 z = node_min.Z; - - noise_seabed->perlinMap2D(x, z); - - // Cave noises are calculated in generateCaves() - // only if solid terrain is present in mapchunk - - noise_filler_depth->perlinMap2D(x, z); - - //printf("calculateNoise: %dus\n", t.stop()); -} - - bool MapgenFractal::getFractalAtPoint(s16 x, s16 y, s16 z) { float cx, cy, cz, cw, ox, oy, oz, ow; @@ -474,6 +454,8 @@ s16 MapgenFractal::generateTerrain() s16 stone_surface_max_y = -MAX_MAP_GENERATION_LIMIT; u32 index2d = 0; + noise_seabed->perlinMap2D(node_min.X, node_min.Z); + for (s16 z = node_min.Z; z <= node_max.Z; z++) { for (s16 y = node_min.Y - 1; y <= node_max.Y + 1; y++) { u32 vi = vm->m_area.index(node_min.X, y, z); -- cgit v1.2.3
