asymptote-3.14

[Douglas R. Reno]

New minor version

[Douglas R. Reno]

I'm going to reassign these to the book for now so whoever wants to do them can do them.

In the meantime I will continue working on rivendell, but I do not want to continue holding the project back on important issues.

[Bruce Dubbs]

Now version 3.13.

[pierre]

Taking those for 13.1 release, as Doug cannot do them by lack of time.

Now 3.14.

Release Notes for Version 3.14

• String bracket indexing via operator[] was added.
• A high-performance sphere approximation based on Bezier triangles was implemented for the native renderer and ported to AsyGL.
• A bitmap preview is generated for V3D PDF output so it displays correctly in non-interactive viewers.
• IBL environment names are now output in the V3D header and IBL fixes were made for Vulkan and AsyGL.
• A stack overflow with -render=0 was fixed.
• The Vulkan export now uses tiling with a dynamic viewport and scissor.
• Rendering issues with pixel() were fixed.
• Triangle group rendering and a vertex shader bug in the no-lighting path were fixed in the AsyGL library.
• Threaded renderer crashes on empty scenes and a division by zero were fixed.
• Surfaces are no longer interpolated as periodic unless they really repeat, and the parametric surface() constructor in graph3 enforces exact endpoint periodicity for periodic splinetypes.
• A bug in the monotonic splinetype was fixed.
• The asyinclude function in the slide module now restores currentlight, currentpen, and currentprojection.
• Documentation and build issues were addressed.

Release Notes for Version 3.13

• Memory usage for complex 3D scenes was greatly reduced.
• The default render setting was changed to 2 for all output formats.
• Meshpens for triangular patches are now handled.
• A Vulkan offscreen resolution mismatch with OpenGL was fixed.
• An OpenGL export bug was fixed.
• VMA C++ wrappers were fixed to use nullptr instead of VK_NULL_HANDLE.
• SSBO reads in the vertex stage now support vertexPipelineStoresAndAtomics.
• The v3d.asy EOF check was fixed.
• Readline history deallocation was fixed.
• The PERL interpreter was removed from the build system.
• The FAQ documentation was migrated from bfnn to texinfo.
• A devcontainer was set up for sandboxed development, including support for lavapipe software rendering.
• Build issues were addressed.

Release Notes for Version 3.12

• A Vulkan renderer was implemented, with a dynamically loaded OpenGL fallback.
• SRGB color space rendering is supported via settings.srgb.
• HiDPI displays are handled for both renderers via settings.devicepixelratio.
• A -vsync option was added.
• The fitscreen modes were fixed.
• PBR material lookup was moved from the fragment shader to the vertex shader, eliminating per-fragment SSBO reads and branching.
• Emissive PBR lighting now supports nolight.
• The V3D serialization reads version 1-2 and writes 2, which includes a lightOn parameter to support unlit emissive per-vertex colors.
• The contour module is now scale invariant and avoids duplicate segments.
• The fuzz normalization in lineintersections was fixed.
• Intersection and symmetric difference operators were added to the geometry module.
• The bundled GLEW library was updated to version 2.2.0.
• Obsolete OSMesa support was removed.
• Third-party licenses can be displayed with --licenses=full.
• The CMake build was optimized.
• The OpenGL export flash was fixed.
• The imageURL option was added to the asy man page.
• Fast Approximate Anti-Aliasing (FXAA) is available as a post-processing option for Vulkan.
• Software Vulkan fallbacks are implemented for macOS Intel systems when Metal is unavailable and for Windows systems without a hardware GPU; this requires downloading the corresponding dynamic library.
• Various compilation issues under macOS and MSWindows were addressed.
• A security measure disables libcurl after input() reads any local file; this can be overridden with -curlAfterRead.

Release Notes for Version 3.11

• A collections library introduces hash maps, hash sets, sorted sets, queues, and B-tree maps (which maintain sorted order) as templated modules, along with iterator utilities such as zip and enumerate.
• User-defined structs can now be iterated with range-based for loops via operator iter, support bracket indexing through operator[] and operator[=], and benefit from native hashing of ints, strings, reals, and int arrays.
• The legacy getopt fallback was removed.
• Rendering issues were addressed.
• The documentation was reorganized.

Fixed at 0d6d8396f277, but needs to be adapted to link against vulkan.
