Shader functionality is not available on OpenGL 1.1

Those functions are intended for advanced users that want full control over the frame processing

Following functions implemented in module [utils]

GetFileSize() conflicts with windows.h)

It can be useful when using basic shapes and one single font,

These functions do not require GPU access

Some strings allocate memory internally for returned strings, just be careful!

Helper types to be used instead of array return types for *ToFloat functions

Angle is calculated from origin point (0, 0)

Parameters need to be normalized

Assumes P is on the plane of the triangle

We are avoiding calling other raymath functions despite available

When multiplying matrices... the order matters!

visibility(default) attribute makes symbols "visible" when compiled with -fvisibility=hidden

Some driver implementation do not support it, despite they should

Be careful with text, every letter maps to a quad

On HTML5 (emscripten) this is allocated on heap,

Only texture changes register a new draw, other state-change-related elements are not

Organized by priority level

Support depends on OpenGL version

By default up to 8 color channels defined, but it can be more

This functions are used to completely abstract raylib code from OpenGL layer,

rlgl provides a default render batch to behave like OpenGL 1.1 immediate mode

OpenGL ES 2.0 can be enabled on Desktop platforms,

VAO functionality is exposed through extensions (OES)

Instancing functionality could also be available through extension

We transpose matrix with multiplication order

The provided angle must be in degrees

We transpose matrix with multiplication order

We transpose matrix with multiplication order

If left-right and top-botton values are equal it could create a division by zero,

We store current viewport dimensions

In all three cases, vertex are accumulated over default internal vertex buffer

Depth increment is dependant on rlOrtho(): z-near and z-far values,

Vertex position data is the basic information required for drawing

We add +1 vertex to the check for security

Texture coordinates are limited to QUADS only

Normals limited to TRIANGLES only?

If quads batch limit is reached, we force a draw call and next batch starts

One color buffer is always active by default

Maximum number of draw buffers supported is implementation dependant,

glPolygonMode() not available on OpenGL ES

Here there are the details with a sample output:

All shapes/models triangles are drawn CCW

External loader function must be provided

glad is generated and contains only required OpenGL 3.3 Core extensions (and lower versions)

Check for additional OpenGL ES 3.0 supported extensions:

Support GLAD loader for OpenGL ES 3.0

We have to duplicate string because glGetString() returns a const string

Only check on OpenGL ES, OpenGL 3.3 has VAO support as core feature

emscripten does not support VAOs natively, it uses emulation and it reduces overall performance...

Fails in WebGL, omitted

Only check on OpenGL ES, OpenGL 3.3 has NPOT textures full support as core feature

Anisotropy levels capability is an extension

Default texture is a 1x1 pixel UNCOMPRESSED_R8G8B8A8

We require a pointer to reset batch and increase current buffer (multi-buffer)

If there is not vertex data, buffers doesn't need to be updated (vertexCount > 0)

If no data changed on the CPU arrays --> No need to re-update GPU arrays (use a change detector flag?)

glMapBuffer() causes sync issue

Batch system accumulates calls by texture0 changes, additional textures are enabled for all the draw calls

The final parameter tells the GPU the offset in bytes from the

Stereo rendering is checked inside

Stereo rendering is checked inside

Added pointer math separately from function to avoid UBSAN complaining

glTexParameteri does NOT affect texture uploading, just the way it's used

OpenGL ES 2.0 with no GL_OES_texture_npot support (i.e. WebGL) has limited NPOT support, so CLAMP_TO_EDGE must be used

If using negative texture coordinates (LoadOBJ()), it does not work!

If mipmaps were not in data, they are not generated automatically

We let the implementation to choose the best bit-depth

A renderbuffer is simpler than a texture and could offer better performance on embedded devices

Cubemap data is expected to be 6 images in a single data array (one after the other),

Added pointer math separately from function to avoid UBSAN complaining

We don't know safely if internal texture format is the expected one...

on OpenGL ES 2.0 (WebGL), internalFormat must match format and options allowed are: GL_LUMINANCE, GL_RGB, GL_RGBA

Requires extension OES_texture_float

Only supports GPU mipmap generation

Using texture id, we can retrieve some texture info (but not on OpenGL ES 2.0)

Each row written to or read from by OpenGL pixel operations like glGetTexImage are aligned to a 4 byte boundary by default, which may add some padding

This behaviour could be conditioned by graphic driver...

Alpha value has already been applied to RGB in framebuffer, we don't need it!

image data should be freed

No textures attached

Attach type: 0-Color, 1-Depth renderbuffer, 2-Depth texture

All attached textures/cubemaps/renderbuffers are also deleted

If not vertex shader is provided, use default one

If not vertex shader is provided, use default one

We detach shader before deletion to make sure memory is freed

This information is useful for debug...

Default attribute shader locations must be Bound before linking

If some attrib name is no found on the shader, it locations becomes -1

All uniform variables are intitialised to 0 when a program links

If GL_LINK_STATUS is GL_FALSE, program binary length is zero
