Constructors/Destructors

Returs the first contiguous string of decimal, numerical characters in the buffer and returns that character string (which atof() can be applied to).

Returns a ptr to the first non-whitespace character in a string

Update the atlas - Resize atlas if needed - Assign new nodes to atlas - Update atlas mapping and pools

ValidateGraph Validate the OptiX scene graph, last step before rendering.

Must have enough bits available with ensureBits */

Get RGBA16 color of pixel with index i (y * width + x) from the raw image with given color type, but the given color type must be 16-bit itself.*/

recursive Returns true if the given pool reference is at level = 0.

like lodepng_chunk_create but with custom allocsize */

Return 4-byte long int whose bytes match the first 4 ASCII chars of string given.

trim from both ends

Destroy all channels

Gets the number of nodes at a given level. If the number of nodes is greater than INT_MAX, prints an error and returns false; otherwise, returns true

Create the Huffman tree given the symbol frequencies*/

Measure GVDB topology & data

Read render buffer to CPU

Read a shader file into a character string

Set the current color channel for rendering

also appends null termination character*/

checks if the colortype is valid and the bitdepth bd is allowed for this colortype. Return value is a LodePNG error code.*/

color is not allowed to already exist. Index should be >= 0 (it's signed to be compatible with using -1 for "doesn't exist") Returns error code, or 0

See ensureBits documentation above. This one ensures up to 25 bits */

See ensureBits documentation above. This one ensures up to 9 bits */

Res of single brick, without apron

Dimension of entire atlas, without aprons

Get RGBA8 color of pixel with index i (y * width + x) from the raw image with given color type.*/

Gets the branching factor per side (number of child nodes or child voxels per side) of a node at the given level.

returns the code. The bit reader must already have been ensured at least 15 bits */

Return the CRC of the bytes buf[0..len-1].*/

Get bits without advancing the bit pointer. Must have enough bits available with ensureBits. Max nbits is 31. */

returns 1 if success, 0 if failure ==> nothing done*/
