ldk_renderer_submit_water

Submit a horizontal world-space grid. XZ positions come from the mesh; the shader supplies Y using water_level and the three waves. Scene depth is sampled after opaque rendering. Meshes and optional textures remain caller-owned and must live until render_frame() completes. Overlapping water surfaces are composited in submission order; this path does not sort stacked water.

LDK_API bool ldk_renderer_submit_water(
 LDKRenderer *renderer,
 LDKRendererViewId view_id,
 LDKResourceMesh mesh,
 const LDKRendererWaterDesc *desc
);

ldk_renderer_water_desc_defaults

Initialize defaults for renderer water.

LDK_API void ldk_renderer_water_desc_defaults(LDKRendererWaterDesc *desc);

ldk_renderer_water_desc_is_valid

Check whether the renderer water desc is valid.

LDK_API bool ldk_renderer_water_desc_is_valid(const LDKRendererWaterDesc *desc);
