# OpenGL Ever needed GLSL hilighting+autocomplete in Notepad++? Try this.

## Recommended Posts

I wrote these about a year ago when I was having trouble focusing on other stuff and they've been lying in wait on my hard drive ever since. This is a hopefully complete autocomplete and syntax hilighting script for Notepad++ up to OpenGL 4.3, inclusive. See attached files.

Here's a copy-paste of the How To Use also present in userDefineLang.xml. Reading this is highly recommended since it may require some manual copy-pasting in case you're using other custom hilighting.

			-------  HOW TO USE -------

1) installing
- if you are using any other custom hilighting in Notepad++, then you need to
copy the contents of this file *between the <NotepadPlus>* tags into your
existing userDefineLang.xml

if you're not using any other custom hilighting, you can simply copy this file to
the following location:

Run Prompt (Win + R) -> %appdata%/Notepad++

- the related auto-complete file needs to be copied to:

[Notepad++ install directory]/Plugins/APIs

usually this is one of the following:

C:\Program Files (x86)\Notepad++\plugins\APIs
C:\Program Files\Notepad++\plugins\APIs

2) using
- once installed, GLSL will show up underneath "Define your language..." in the
Language menu in Notepad++. Notepad++ needs to be restarted for the option to show
up.

3) enabling auto-complete
- auto-complete may not be enabled by default in Notepad++. To enable it, run Notepad++,
navigate to

Settings -> Preferences -> Backup/Autocompletion

and check the following:

* Enable auto-completion on each input
* Function parameters hint on input

Leave the radio button on Function completion

4) oh-oh, and if you don't have Notepad++, get it from here:

- http://notepad-plus-plus.org/download/

5) auto-complete function hints format
- the auto-complete tips contain a lot of information that has been compressed into a small
number of characters. Knowing the format will help with productivity and consistency.
A generalized form of a hint is as follows:

{DEPRECATED}{REQUIRED_MODULES}[MIN_VERSION {to MAX_VERSION}/DOUBLE_MIN_VERSION] HINT

* DEPRECATED denotes that the entry is deprecated in the latest version of GLSL. Its
use may or may not be possible based on GLSL's deprecation model

* REQUIRED_MODULES (only present when relevant) can be:

FRAGMENT, VERTEX, TESSELATOR, COMPUTE, etc.

* MIN_VERSION notes the minimum GLSL (not OpenGL!) version required to use this entry

* MAX_VERSION (only present when relevant) indicates deprecation

* DOUBLE_MIN_VERSION is only present for relevant entries and may be set to '-', which
indicates that while eligible, no double-precision overload of this function is
explicitly defined



This isn't something I'm supporting or whatnot and it hasn't been error-checked by a third party, although tried to be as diligent as possible to weed out as many mistakes as possible.

I hope someone finds this useful.

Edit: note that the syntax hilighting is not complete - swizzle operators and such are a mess and don't parse well at all without context-sensitive information, which Notepad++ doesn't have. For general use it should suffice, though.

• Hello! As an exercise for delving into modern OpenGL, I'm creating a simple .obj renderer. I want to support things like varying degrees of specularity, geometry opacity, things like that, on a per-material basis. Different materials can also have different textures. Basic .obj necessities. I've done this in old school OpenGL, but modern OpenGL has its own thing going on, and I'd like to conform as closely to the standards as possible so as to keep the program running correctly, and I'm hoping to avoid picking up bad habits this early on.
Reading around on the OpenGL Wiki, one tip in particular really stands out to me on this page:
For something like a renderer for .obj files, this sort of thing seems almost ideal, but according to the wiki, it's a bad idea. Interesting to note!
So, here's what the plan is so far as far as loading goes:
Set up a type for materials so that materials can be created and destroyed. They will contain things like diffuse color, diffuse texture, geometry opacity, and so on, for each material in the .mtl file. Since .obj files are conveniently split up by material, I can load different groups of vertices/normals/UVs and triangles into different blocks of data for different models. When it comes to the rendering, I get a bit lost. I can either:
Between drawing triangle groups, call glUseProgram to use a different shader for that particular geometry (so a unique shader just for the material that is shared by this triangle group). or
Between drawing triangle groups, call glUniform a few times to adjust different parameters within the "master shader", such as specularity, diffuse color, and geometry opacity. In both cases, I still have to call glBindTexture between drawing triangle groups in order to bind the diffuse texture used by the material, so there doesn't seem to be a way around having the CPU do *something* during the rendering process instead of letting the GPU do everything all at once.
The second option here seems less cluttered, however. There are less shaders to keep up with while one "master shader" handles it all. I don't have to duplicate any code or compile multiple shaders. Arguably, I could always have the shader program for each material be embedded in the material itself, and be auto-generated upon loading the material from the .mtl file. But this still leads to constantly calling glUseProgram, much more than is probably necessary in order to properly render the .obj. There seem to be a number of differing opinions on if it's okay to use hundreds of shaders or if it's best to just use tens of shaders.
So, ultimately, what is the "right" way to do this? Does using a "master shader" (or a few variants of one) bog down the system compared to using hundreds of shader programs each dedicated to their own corresponding materials? Keeping in mind that the "master shaders" would have to track these additional uniforms and potentially have numerous branches of ifs, it may be possible that the ifs will lead to additional and unnecessary processing. But would that more expensive than constantly calling glUseProgram to switch shaders, or storing the shaders to begin with?
With all these angles to consider, it's difficult to come to a conclusion. Both possible methods work, and both seem rather convenient for their own reasons, but which is the most performant? Please help this beginner/dummy understand. Thank you!

• I want to make professional java 3d game with server program and database,packet handling for multiplayer and client-server communicating,maps rendering,models,and stuffs Which aspect of java can I learn and where can I learn java Lwjgl OpenGL rendering Like minecraft and world of tanks

• A friend of mine and I are making a 2D game engine as a learning experience and to hopefully build upon the experience in the long run.

-What I'm using:
C++;. Since im learning this language while in college and its one of the popular language to make games with why not.     Visual Studios; Im using a windows so yea.     SDL or GLFW; was thinking about SDL since i do some research on it where it is catching my interest but i hear SDL is a huge package compared to GLFW, so i may do GLFW to start with as learning since i may get overwhelmed with SDL.
-Questions
Knowing what we want in the engine what should our main focus be in terms of learning. File managements, with headers, functions ect. How can i properly manage files with out confusing myself and my friend when sharing code. Alternative to Visual studios: My friend has a mac and cant properly use Vis studios, is there another alternative to it?

• Both functions are available since 3.0, and I'm currently using glMapBuffer(), which works fine.
But, I was wondering if anyone has experienced advantage in using glMapBufferRange(), which allows to specify the range of the mapped buffer. Could this be only a safety measure or does it improve performance?
Note: I'm not asking about glBufferSubData()/glBufferData. Those two are irrelevant in this case.

Before using void glBindImageTexture(    GLuint unit, GLuint texture, GLint level, GLboolean layered, GLint layer, GLenum access, GLenum format), does need to make sure that texture is completeness.
