3dworld's Issues

defs.h(55,10): fatal error C1083: Cannot open include file: 'assimp/config.h': No such file or directory

J:\tools\3DWorld-2222\3DWorld-master\dependencies\assimp\include\assimp\defs.h(55,10): fatal error C1083: Cannot open include file: 'assimp/config.h': No such file or directory (compiling source file src\assimp_wrap.cpp)

Completion of error handling

Would you like to add more error handling for return values from functions like the following?

• fclose ⇒ texture_t::write_to_bmp
• fseek ⇒ ImageGetRow

Compilation, Makefile and README.linux

Edit: I rephrase because I was in urge and I had not time to read myself the 1st time.

Compilation problem

SHA1 2f36272 The compilation is broken with gli. I tried the currently present folder then the git cloned version but got the same problem:

In file included from dependencies/gli/gli/format.hpp:6:0,
                 from dependencies/gli/gli/gli.hpp:39,
                 from src/image_io.cpp:25:
dependencies/gli/gli/type.hpp:42:24: error: ‘qualifier’ has not been declared
  template <typename T, qualifier P>

I have a Debian 9.8, amd 64, and g++-6.0. I dunno yet how to fix this.
Note that glib compiles well by itself.

Some confusing points inside the README.linux:

• Please tell in the README.linux to download glui and gli at the root of the project (next to src/). This is not obvious. Then, I find this sad not to download these libs directly inside the dependencies/ folder. In the case of clone inside this folder, we have to update the Makefile:

GLUI=../dependencies/glui
GLI=../dependencies/gli

• these instructions:

Build setup:
mkdir lib
mkdir obj
cd obj
ln -s ../makefile .

are not clear because we do not know if they refer to gli or 3DWorld. You should seperate them with sections. You also can remove these instructions because I explain just after how to simply you Makefile.

Some confusing points inside the Makefile

• Why the binary 3dworld is created inside the lib/ folder? It should be created in any folder (obj/, the root project ...) execpt this one!
• CPP is working but it's badly located inside the Makefile. Better to place it before at the first line.
• your all: rule is not good for managing obj and lib directories. You should simply try the following code (explainations come just after):

BUILD=obj/
VPATH=$(BUILD):src

all: $(TARGET)

%.o : %.C $(BUILD)/%.d
	$(CPP) $(CPPFLAGS) -MMD -c $< -o $(abspath $(BUILD)/$@)
%.o : %.cc $(BUILD)/%.d
	$(CPP) $(CPPFLAGS) -MMD -c $< -o $(abspath $(BUILD)/$@)
%.o : %.cpp $(BUILD)/%.d
	$(CPP) $(CPPFLAGS) -MMD -c $< -o $(abspath $(BUILD)/$@)

$(OBJS): | $(BUILD)
$(BUILD):
	@mkdir -p $(BUILD)

Explainations:
Firstly, feel free to rename BUILD variable, it indicates the folder holding your *.o files. You have to refer this folder to VPATH. The all: rule now simply depends on your binary file. For compiling your c(pp) files you have to add the -ooption else *.o are created next to your Makefile instead of inside $(BUILD) folder. Note that you also have to depend of %.d files, so added them in the dependency rule. I added abspath but this is optional but this helps coverage tool like gcov to find the source. Finaly $(OBJS): | $(BUILD)replace your if then else. $(BUILD) rule is called before building $(OBJS). Also note that you no longer need of ../../ for TARGA, GLUI ...

• Unfortunaltly there are still problems with *.d files: they are created at the root of the directory and makefile will recompiling all c(pp) files everytime. So replace your code based on touch/cat commands by this code which does the same thing:

$(BUILD)/%.d: ;
.PRECIOUS: $(BUILD)/%.d
-include $(patsubst %,$(BUILD)/%.d,$(basename $(OBJS)))

With all these changes you simply can go to the root of the project and type make! No more ln or mv :)

• Make clean can now simply remove the folder $(BUILD).
• I attached my Makefile to this issue. makefile.txt Note: because of github I had to add the .txt extension else it refuses to attach it.

As said previously I could not finish compiling because of gli so I cannot check if my Makefile is fully correct. For more information you can see my Makefile repo.

chmod

• There are plenty of ASCII files in executable mode. You should fix their rights with a chmod 644 git manages the chmod rights.

I can compatible 64-bit debug libraries for OpenAL

let me help u.
https://github.com/kcat/openal-soft.git
im sure you can git clone from this site, and debug it using x64 debug enviroment.

not an issue :)

Hello! Juris from Latvia here, haven't been checking on your project for a while (in fact, making some UE4 assets now myself). How are you, what are advances in 3D World? My best wishes to you, be healthy!
And - Happy Easter !

Just informing

Oh, probably need to state visible somewhere at release - "Press F1 after starting particular config"
City is working, with cars and yellow balls pedestrians :)
I could list ones that does not start:
Config Universe, River, Berkeley, Puget, Puget Sound, Grand Canyon, Grand Canyon Sound, Hetch, Config Soda, San Miquel, White Plane.
He
3DWorld_2019-06-23.zip
re I will attach some screens, please take a look, maybe something visual missing or wrong.

Hi. I press F1 when i in the scene, but can not change to the other world_model.

its seems like the universe_only mode was set, then how i can change my config?

A bigger demo?

I saw the mod Grand Theft Auto: Stars & Stripes. It could be taken down for copyright infringement any time. I am thinking about building something in real world and inexperienced in 3D stuff. In my opinion, if there is a 1:1 Hawaii built with your program, it could be noticed. How do you think?

Better Graphics???

It's not bad but don't you think that it could render even more realistic graphics?

Remove an unnecessary null pointer check

An extra null pointer check is not needed in a function like the destructor for the class “VertData”.

How to build from source on MSYS2 MINGW64?

Support AVIF

In some sources, it is more advanced than WebP. So I think AVIF format can be supported.

Compiling errors when using the command

HI dear author,
It's truly a honor to write a letter to you, I'm build your project nowadays and found the error when building as following, I wonder if there is a chance that you know the reason? :)

thank you
best regards to you
William

can you list your DLL file to execute .exe of this project?

Its my pleasure to meet you.
I debug this project, but some DLL may not exsit in my Ouput file, then the 3DWorld.exe can not run.

reserved identifier violation

I would like to point out that identifiers like “_ASTEROID_H_” and “_BUILDING_H_” do not fit to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?

Can you help me with this issue?

I downloaded the project and exe from release. When I run exe I got this error:

C:\Users\janis>C:\Users\janis\Downloads\3DWorld-master\3DWorld-master\3DWorld.exe
Starting 3DWorld
*** Error: Could not open input configuration file file 'scene_config/config_pre.txt'.
*** Error: Could not open input configuration file file 'scene_config/config_post.txt'.

Error when building on Linux

I am not using Ubuntu or any Debian offspring. I use Arch Linux, so I skipped that “Install (Ubuntu):” part. Libraries with those names do not exist in Arch Linux repositories.

Character animation without rigging

I found Idea for character animation without rigging or bones. This idea created by pixar studios called character articulation through profile curves or Curvenent system.
They have been released the paper about this idea, So please if you able to do this as standalone free software for Windows OS, It will be great

Look at the video and download the paper too

https://youtu.be/gUJ4RxMdVn8

Download the paper here :-

Please answer me for important.

Thank you

Windows test run

I have very egoistic lazy proposition :) How about upload time to time some Windows compiled executable? ;-) I know, options are now in manual editing .ini, so it is not that straightforward maybe.... but what Author says about such idea? :) Thanks.
