* [core] improve legibility of labels that follow linesAnsis Brammanis2017-07-113-5/+23
| | | | | | | | | | port https://github.com/mapbox/mapbox-gl-js/pull/4781 This improves legibility of labels that follow lines in pitched views. The previous approach used the limited information in the shader to calculate put the glyph in approximatelyright place. The new approach does this more accurately by doing it on the cpu where we have access to the entire line geometry.
* [core] Bind only active attributes in order to avoid exceeding attribute ↵Lauren Budorick2017-06-293-6/+64
| | | | | limits (#9373) Introducing two new attributes to enable property functions for line-width (#9250) pushed the attribute count over GL_MAX_VERTEX_ATTRIBS on some devices. Now we selectively bind only attributes that are used, making it unlikely to surpass GL_MAX_VERTEX_ATTRIBS.

* [core] store vertex attribute binding to prevent duplicate bindsKonstantin Käfer2017-06-131-0/+1
| | | | | | | | | We have an "oldBinding" value that we use for checking whether the vertex attribute was already bound to the current VAO, but we never set the state. Additionally, we're also checking whether the previous state was already any binding (optional is set), and don't re-enable the vertex attribute array. Additionally, we now only disable the vertex attribute array when the previous state was in fact an array attribute. We still don't deduplicate constant glVertexAttrib* calls, but that's a little trickier.

* | [core] Refactor OpenGL extension loading mechanismKonstantin Käfer2017-03-2318-359/+434
| | | | | | | | Previously, we initialized global variables that held pointers to the extension functions. While this seemed to work, the spec doesn't guarantee that the function pointers are identical for different OpenGL contexts. Therefore, we are now making them a member variable of the Context object.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PaintPropertyBinder and subclass templates were being instantiated for every unique attribute type (e.g. a_color, a_fill_color, a_halo_color) even though they behave identically for a given property value type (e.g. Color). To fix this, a unique type such as a_color no longer derives from gl::Attribute<...> -- instead it has an inner Type typedef, which should be used wherever neither a unique type nor attribute name is required.

* Pack min + max into one attribute :muscle:Molly Lloyd2017-03-082-13/+35
| | | | | | | | Some devices supported by Mapbox GL provide only 8 vertex attributes; this change packs existing attributes to get us just under that limit. For properties using a composite function, pack the min and max values into a single attribute with two logical components instead of using two separate attributes and buffers. Special logic is included for color attributes, whose integer components must be packed into the available bits of floating-point attributes. (We don't have access to ivec types in GL ES 2.0.) For source functions, continue to bind just a one-component attribute even though the GLSL type is vec2 (or vec4 for colors). The type-checking done by gl::Attribute is relaxed slightly to accommodate this.

* [core] Return to static, per-segment approach to VAOsJohn Firebaugh2016-11-153-42/+10
| | | | This is safer now -- it can be an implementation detail of Segment/Context. And the typing of SegmentVector now ensures that the attributes and program match.

|
* [core] Assign attribute locations sequentiallyJohn Firebaugh2016-11-155-11/+21
| | | | | | | Two reasons to prefer explicit sequential location assignment, rather than relying on the GLSL linker to assign locations: * For data-driven properties, we want to have the option to use glDisableVertexAttribArray plus glVertexAttrib*. In order to use glDisableVertexAttribArray, we must avoid using attribute location 0, which cannot be disabled. * We want to use the same VAO in cases where, say, a fill layer might be rendered with FillProgram at first, and then FillPatternProgram later. VAOs do not store the program binding, only the attribute bindings, so as long as the two programs have the same attributes and attribute locations, only a single VAO (per segment) is needed.
